the company.

                               New York, NY 10001

                                 PROXY STATEMENT

      This statement is furnished in connection with the solicitation by the
Board of Directors of Tridan Corp., a New York corporation (the "Company") of
proxies to be voted at the Annual Meeting of Shareholders to be held June 17,
2008 and any and all adjournments thereof, for the purposes set forth in the
accompanying Notice of Annual Meeting of Shareholders. This Proxy Statement is
being mailed to shareholders on or about May 30, 2008.

      All proxies which have been properly executed and received by the time of
the meeting will be voted at the meeting in accordance with the instructions
thereon. Any shareholder executing a proxy may revoke it in writing by execution
of another proxy or by any other legal method at any time before the shares
subject to the proxy are voted at the meeting. The Board of Directors recommends
that shares be voted, and if no choice is specified on the proxy, the shares
will be voted FOR the election as directors of the nominees hereinafter named,
FOR ratification of the selection of Weiser LLP, as auditors, and in the
discretion of the proxy holders on such other matters as may properly come
before the meeting.

      As of May 16, 2008, there were issued and outstanding 3,107,865.3954
shares of capital stock, par value $.02 per share, of the Company, which is the
only class of capital stock of the Company. Shareholders will be entitled to one
vote for each share held, with pro rata voting rights for any fractional shares.
Holders of record of such shares at the close of business on May 16, 2008 will
be entitled to vote at the meeting.

      The participants in the Tridan Corp. Employees' Stock Ownership Trust are
the beneficial shareholders of the shares held under the Trust, and the shares
held for such participants will be voted only if and as directed by the
participant for whose account such shares are held of record by the trustees of
the Trust. Accordingly, the attached Notice, this Proxy Statement and the form
of proxy have been mailed to each person who was a participant on the record
date, and the shares beneficially owned by such participants will be voted in
accordance with their proxies.

      The Company will pay the cost of preparing, assembling, and mailing the
form of proxy and the material used in connection with solicitation of proxies.
In addition to solicitation by use of the mails, certain officers and directors
of the Company, who will receive no compensation for their services (other than
their regular compensation) may solicit the return of proxies personally or by
telephone or telegraph.

      An Annual Report covering the operations of the Company for its fiscal
years ended April 30, 2008 and 2007 is enclosed herewith, but does not
constitute a part of the material for the solicitation of proxies.



                              ELECTION OF DIRECTORS

      At the meeting, six directors are to be elected to hold office until the
next Annual Meeting of Shareholders and until their respective successors shall
have been chosen and qualified, or as otherwise provided in the By-Laws of the
Company. The election of a Board of Directors will require the vote of a
majority of the shares present in person or by proxy at the meeting.

      It is intended that the persons named in the accompanying proxy will vote
such proxy, if signed and returned, for the election of the nominees listed
below. If for any reason any of said nominees shall become unavailable for
election, which is not anticipated, the proxies may be voted for a substitute
nominee designated by the Board of Directors. The Board of Directors has no
reason to expect that any of the nominees will fail to be a candidate at the
meeting and, accordingly, does not have in mind any substitute.

      As of May 16, 2008, Peter Goodman owned beneficially 1,276,910.73 shares
(41%) of the Company, which does not include shares owned by Barbara S. Goodman,
Peter Goodman's wife, nor shares owned by them as trustees for his brother
Thomas Goodman.

      The following Tables A and B set forth information concerning directors
and nominees for election as director for a term of one year. Table C sets forth
information concerning non-director officers of the Company. The Table A
nominees (Mark Goodman, Peter Goodman and Warren Pelton) are "interested
persons" as defined in Section 2(a)19 of the Investment Company Act of 1940, and
the Table B nominees (Messrs. Kramer, Negin and Stoever) are not. Peter Goodman
is an "interested person" because he is an officer and holder of more than 5% of
the shares of the Company, Mark Goodman because he is Peter Goodman's son, and
Warren Pelton because he is an officer of the Company.

                  COMPENSATION OF DIRECTORS AND EXECUTIVE OFFICERS

      No director or officer received any compensation from the Company during
the last fiscal year, except for the fees of $12,000 paid during each year to
each director, plus an additional $5,000 to Paul Kramer as chairman of the audit
committee. The Company does not have any bonus, profit sharing, or other
compensation plan, contract or arrangement with anyone, nor any pension or
retirement plan; nor has the Company ever granted to anyone any options,
warrants or other rights to purchase securities.

      All executive officers of the Company as a group (two persons) received
compensation (comprised solely of said directors' fees) aggregating $24,000
during fiscal 2008 (which excludes professional fees paid to the law firm of
which I. Robert Harris, secretary of the Company, is a member).

                                   COMMITTEES

Audit Committee

      The Audit Committee consists of three directors appointed by the board,
namely Paul Kramer, Chairman, Jay S. Negin and Russell J. Stoever, each of whom
is independent as defined in Rule 4200(a)(15) of the NASD listing standards. The
board has determined that Mr. Kramer qualifies as an Audit Committee financial
expert, as defined by applicable SEC rules and regulations. The Audit Committee
operates under its charter, which it reviews annually and which is then
submitted for approval by the Board of Directors. A copy of the charter is
attached as an appendix to this proxy statement.

      The Audit Committee assists the Board of Directors in fulfilling their
oversight responsibilities relating to the quality of the Company's accounting
and auditing practices, including its financial statements and financial
reporting process, disclosure controls and procedures and internal control over
financial reporting, the annual independent audit of the Company's financial
statements, and compliance with the Company's ethics program and with regulatory
requirements. The Audit Committee is directly responsible for the appointment,
compensation and oversight of the Company's independent registered public
accounting firm. The committee met three times during the fiscal year ended
April 30, 2008.

Audit Committee Report

      The Audit Committee has reviewed and discussed the Company's April 30,
2008 audited financial statements with management and with Weiser LLP, the
Company's independent registered certified public accountants. The Audit
Committee has also discussed with said auditors the matters required to be
discussed by Statement on Auditing Standards No. 61, as amended by statements on
Auditing Standards Nos. 89 and 90, has received from them the written
disclosures and letter required by Independence Standards Board Standard No. 1,
and has discussed with them their independence from the Company. The Audit
Committee met separately with the independent registered certified public
accountants, with and without management, to discuss the results of their
examination and their observations and recommendations. Based on the foregoing
review and discussions, the Audit Committee has recommended to the Board that
the audited financial statements as of April 30, 2008 be issued to shareholders
and filed with the SEC.

      Audit Committee Members:

         Paul Kramer, Chairman
         Jay S. Negin
         Russell J. Stoever

Nominating Committee

      The Company does not have a standing nominating committee, because of the
small size of the Board of Directors and the infrequency of its turnover.
Rather, on those rare occasions when a new candidate is proposed for
consideration, whether by a shareholder or by others, the entire board considers
the candidate and the board itself acts as a nominating

                                      - 5 -



committee. The board considers a candidate's, experience, familiarity with
business and investments, knowledge about issues affecting the Company, and
willingness to spend the time necessary to read applicable materials and attend
meetings. In instances where the board determines that a candidate will be a
valuable replacement or addition to the Board of Directors, the board recommends
such candidate's election by the shareholders. This procedure has been followed
successfully and without issue since 1980, when the Company first became a
registered investment company, and the board believes it continues to be
appropriate.

                             ATTENDANCE AT MEETINGS

      During the fiscal year ended April 30, 2008, there were five meetings of
the Board of Directors and three meetings of the Audit Committee. Each of the
directors attended at least 75% of the aggregate number of meetings of the Board
and of the Audit Committee on which he served. Although the Company has no
formal policy regarding director attendance at the annual shareholders meetings,
directors are expected to attend, and all members of the Board attended last
year's annual meeting.

                    SHAREHOLDER COMMUNICATIONS WITH DIRECTORS

      The Board of Directors has not established a formal process for
shareholders to send communications to the Board. In the Board's view, it is
appropriate for the Company not to have such process, because the directors are
few in number, and any shareholder who wishes to do so may address a letter to
the attention of the entire Board, care of the Company at its principal office,
or to individual Board members either at that address or at their personal
addresses listed in the proxy statement.

                      RELATIONSHIP WITH AND RATIFICATION OF
                    INDEPENDENT CERTIFIED PUBLIC ACCOUNTANTS

      The Audit Committee is responsible for approving the engagement of the
Company's independent public accountants prior to their engagement. The Audit
Committee and Board of Directors have unanimously approved the selection of
Weiser LLP as independent public accountants for the Company for the fiscal year
ending April 30, 2009. The former accounting firm of Leslie Sufrin and Company,
P.C., which merged into Weiser LLP, had been the Company's auditors since it
became a registered investment company in 1980. Although shareholder
ratification is not required by law, to be consistent with past practice the
firm's selection is being submitted for ratification by the shareholders, which
requires the affirmative vote of a majority of the shares of the Company present
at the meeting. If shareholders do not ratify their selection, the Board will
reconsider the matter and will decide whether to retain that firm. The Audit
Committee and Board of Directors reviewed the services performed by Weiser LLP
during the last fiscal year and determined that such services did not affect
their independence. The firm has no direct or indirect financial interest in the
Company, except for fees received by it for services which were furnished at
customary rates and terms. Representatives of the firm are expected to be
present at the meeting, will be given an opportunity to make such statements as
they feel appropriate, and will be available to respond to appropriate
questions.

Audit Fees - Weiser LLP billed the Company a total of $41,000 for the 2008
fiscal year, and $40,000 for the 2007 fiscal year, for the audit of the
Company's annual financial statements and in connection with statutory and
regulatory filings for those years.

Audit-Related Fees - No fees were billed to the Company for the last two fiscal
years for any audit-related services.

Tax Fees - No fees were billed to the Company for the last two fiscal years for
tax compliance, tax advice or tax planning.

All Other Fees - No fees were billed to the Company for the last two fiscal
years for any other services.

                    INVESTMENT ADVISORY AGREEMENT AND ADVISER

      The Company's investment adviser is J.P. Morgan Investment Management
Inc., ("Morgan"), 245 Park Avenue, New York, NY 10167. The Investment Advisory
Agreement dated July 1, 2000 (the "Agreement") between the Company and Morgan
was most recently approved by the shareholders at the annual meeting on June 20,
2000 and expires June 30, 2008. On May 22, 2008, the Board of Directors
(including the Company's independent directors) unanimously approved a
continuation of the Agreement until June 30, 2009 (subject to the early
termination provisions contained in the Agreement).

      Under the Agreement Morgan, subject to the general supervision of the
Company's Board of Directors and in conformance with the stated policies of the
Company, manages investment operations and the composition of the Company's
portfolio of securities and

                                      - 8 -



investments. In this regard, it is the responsibility of Morgan to make
investment decisions for the Company and to place the purchase and sale orders
for the portfolio transactions of the Company.

      As compensation for the services rendered and related expenses borne by
Morgan, the Company, under the Agreement, has paid Morgan an annual fee,
computed and payable quarterly, equal to 0.28% of the Company's net assets under
management. Morgan received fees aggregating $104,183 applicable to the year
ended April 30, 2008.

      The investment advisory services of Morgan to the Company are not
exclusive under the terms of the Agreement. Morgan is free to, and does, render
investment advisory services to others, including numerous funds.

      Morgan seeks to obtain the best price and execution of orders placed for
the Company's assets considering all of the circumstances. If transactions are
executed in the over-the-counter market, Morgan will deal with the principal
market makers, unless more favorable prices and executions are otherwise
obtainable. There is no agreement by Morgan with any broker or dealer to place
orders with it. When circumstances relating to a proposed transaction indicate
that a particular broker or dealer is in a position to provide the best
execution considering all factors including price, the order is placed with that
broker or dealer. This may or may not be a broker or dealer which has provided
statistical or other factual information to Morgan. Subject to the requirement
of seeking the best price and execution, Morgan may, in circumstances in which
two or more brokers are in a position to offer comparable prices and execution,
give preference to a broker or dealer which has provided statistical and other
factual information to it. Morgan is of the opinion that while such information
is useful in varying degrees, it is of indeterminable value and does not reduce
the expenses of Morgan. In recognition of the brokerage execution services
Morgan may pay a brokerage commission in excess of that which another broker
might have charged for the same transaction. Morgan periodically evaluates the
overall reasonableness of brokerage commissions paid by the Company. The factors
considered in these evaluations include the competitive negotiated rate
structure at the time the commission is charged and the effectiveness of the
broker's execution.

      The names and principal occupations of the directors and principal
executive officers of Morgan are as follows. All of them may be reached c/o J.P.
Morgan Investment Management Inc., 245 Park Avenue, New York, NY 10167.

             Report of Independent Registered Public Accounting Firm


To the Shareholders and Board of Directors
Tridan Corp.

We have audited the accompanying  statements of assets and liabilities of Tridan
Corp.  (the  "Company"),  including  the schedules of  investments  in municipal
obligations,  as of April  30,  2008 and 2007,  and the  related  statements  of
operations for the years then ended,  and the statement of changes in net assets
and the  financial  highlights  for the each of the three  years ended April 30,
2008. These financial statements and financial highlights are the responsibility
of the  Company's  management.  Our  responsibility  is to express an opinion on
these financial statements and financial highlights based on our audits.

We conducted our audits in accordance  with the standards of the Public  Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement.  An audit
includes  examining,  on a test  basis,  evidence  supporting  the  amounts  and
disclosures in the financial statements. Our procedures included confirmation of
securities  owned,  as of April 30, 2008 and 2007,  by  correspondence  with the
custodian.  An audit also includes assessing the accounting  principles used and
significant  estimates  made by  management,  as well as evaluating  the overall
financial  statement  presentation.   We  believe  that  our  audits  provide  a
reasonable basis for our opinion.

In our opinion,  the financial  statements and financial  highlights referred to
above present fairly, in all material respects, the financial position of Tridan
Corp. as of April 30, 2008 and 2007,  the result of its operations for the years
then ended,  and the changes in its net assets and its financial  highlights for
each of the three years ended April 30,  2008,  in  conformity  with  accounting
principles generally accepted in the United States of America.

1.    Significant accounting policies

      The following is a summary of the significant accounting policies followed
      by Tridan Corp. (the "Company"), a closed-end,  non-diversified management
      investment  company,  registered under the Investment Company Act of 1940,
      in the preparation of its financial statements.

      Acquisition and valuation of investments

      Investment  transactions  are accounted for on the date the securities are
      purchased/sold  (trade date) and interest on securities  acquired/sold  is
      included in income from/to the settlement date. Short-term investments are
      stated at cost, which is equivalent to fair value.

      Fair values for the Company's  investments in municipal  obligations  have
      been determined  based on the bid price of the obligation.  Securities for
      which  quotations  are not readily  available  are valued at fair value as
      determined by the board of directors.  There were no securities  valued by
      the board of directors,  for which quotations were not readily  available,
      as of April 30, 2008 and 2007.

      Amortization of bond premium or discount

      In determining investment income, bond premiums or discounts are amortized
      over the remaining term of the obligation.

      Income taxes

      It is the Company's policy to comply with the requirements of the Internal
      Revenue Code that are applicable to regulated  investment companies and to
      distribute  substantially  all of its taxable income to its  shareholders.
      Therefore, no income tax provision is required.

      Interest  income from  municipal  investments  are exempt from Federal and
      state income taxes.

      Cash and cash equivalents

      The Company  considers all investments that can be liquidated on demand to
      be cash equivalents.

      Use of estimates

      The  preparation  of financial  statements,  in conformity  with generally
      accepted accounting principles,  requires management to make estimates and
      assumptions that affect the reported amounts of assets and liabilities and
      disclosures  of  contingent  assets  and  liabilities  at the  date of the
      financial  statements and the reported  amounts of increases and decreases
      in net assets from operations during the reporting period.  Actual results
      could  differ  from those  estimates.  Significant  estimates  are used in
      determining the fair value of investments.

      redemption   is  received.   At  April  30,  2008  and  2007,   $1,072,256
      (91,234.6046 shares) and $1,016,426  (86,564.9839  shares),  respectively,
      had been redeemed under this plan and are held in treasury.

      The net asset value per share is calculated by dividing the aggregate fair
      value of all assets less the aggregate  fair value of all  liabilities  by
      the number of common shares outstanding at the end of the period.

      The net asset value per share and the shares outstanding were as follows:

                             AUDIT COMMITTEE CHARTER

Organization

This charter governs the operations of the audit committee. The committee shall
review and reassess the charter at least annually and obtain the approval of the
board of directors. The committee shall be appointed by the board of directors
and shall comprise at least three directors, each of whom is "independent" of
management and the Company. Members of the committee will be considered
independent if they do not receive, other than for service on the board of
directors, any consulting, advisory, or other compensatory fees from the
Company, are not "interested persons" of the Company, as defined in the
Investment Company Act of 1940, and comply with the definition of independence
in Rule 4200(a)(15) of the NASD listing standards. All committee members shall
be financially literate, and at least one member shall be an "audit committee
financial expert" as defined by SEC regulations.

Statement of Policy

The audit committee shall provide assistance to the board of directors in
fulfilling their oversight responsibility to the shareholders, potential
shareholders, the investment community, and others relating to the Company's
financial statements and the financial reporting process, the systems of
disclosure controls and procedures and internal accounting and financial
controls, the annual independent audit of the Company's financial statements,
and compliance with regulatory requirements and with ethics programs as
established by management and the board. In so doing, it is the responsibility
of the committee to maintain free and open communication between the committee,
independent auditors, the internal auditors and management of the Company. In
discharging its oversight role, the committee is empowered to investigate any
matter brought to its attention with full access to all books, records,
facilities, and personnel of the Company and the power to retain outside
counsel, or other experts for this purpose.

Responsibilities and Processes

The primary responsibility of the audit committee is to oversee the Company's
financial reporting process on behalf of the board and report the results of
their activities to the board. While the audit committee has the
responsibilities and powers set forth in this charter, it is not the duty of the
audit committee to plan or conduct audits or to determine that the Company's
financial statements are complete and accurate and are in accordance with
generally accepted accounting principles. Management is responsible for
preparing the Company's financial statements in accordance with generally
accepted accounting principles, and the independent auditors are responsible for
auditing those financial statements. The committee in carrying out its
responsibilities believes its policies and procedures should remain flexible, in
order to best react to changing conditions and circumstances. The committee
should take the appropriate actions to set the overall corporate "tone" for
quality financial reporting, sound business risk practices, and ethical
behavior.

                                      App 1



The following shall be the principal recurring processes of the audit committee
in carrying out its oversight responsibilities. The processes are set forth as a
guide with the understanding that the committee may supplement them as
appropriate and consistent with SEC rules and regulations.

      o     The committee shall have a clear understanding with management and
            the independent auditors that the independent auditors are
            ultimately accountable to the board and the audit committee, as
            representatives of the Company's shareholders. The committee shall
            have the ultimate authority and responsibility to evaluate and,
            where appropriate, replace the independent auditors. The committee
            shall discuss with the auditors their independence from management
            and the Company and the matters included in the written disclosures
            required by generally accepted auditing standards and by applicable
            SEC rules and regulations. Annually, the committee shall review and
            recommend to the board the selection of the company's independent
            auditors, subject to shareholders' approval.

      o     The committee shall discuss with the Company's administrator and
            independent auditors the overall scope and plans for their
            respective audits, and any other services to be performed by them,
            including the adequacy of staffing and compensation, all of which
            services shall be subject to the committee's approval. Also, the
            committee shall discuss with them the auditors' report on the
            adequacy and effectiveness of disclosure controls and procedures and
            internal control over financial reporting. The committee shall also
            review with the auditors the Company's system to monitor and manage
            business risk, and legal and ethical compliance programs.

      o     The committee shall review the interim financial statements with
            management and the independent auditors prior to their issuance.
            Also, the committee shall discuss the results of their review and
            any other matters required to be communicated to them by the
            independent auditors under generally accepted auditing standards.
            The chair of the committee may represent the entire committee for
            the purposes of this review.

      o     The committee shall review with management and the independent
            auditors the financial statements to be included in the Company's
            annual report to shareholders, including their judgment about the
            quality, not just acceptability, of accounting principles, the
            reasonableness of significant judgments, and the clarity of the
            disclosures in the financial statements. The committee shall
            recommend to the board whether the audited statements shall be
            issued to the shareholders and filed with the SEC. Also, the
            committee shall discuss the results of the annual audit and any
            other matters required to be communicated to the committee by the
            independent auditors under generally accepted auditing standards and
            applicable SEC rules and regulations.
