                               SEMI-ANNUAL REPORT

Dear Shareholder:

      This semi-annual  report of Tridan Corp.  covers the six-month period from
May 1,  2007 to  October  31,  2007.  As part of this  report,  we  enclose  the
unaudited  financial report for that six-month period and for the  corresponding
period in 2006.

      A schedule  of the  company's  portfolio  holdings  at October  31,  2007,
consisting  entirely of  municipal  obligations,  is  included in the  financial
report. The company invests  exclusively in non-voting  securities.  The company
files its  complete  schedule of  portfolio  holdings  with the  Securities  and
Exchange Commission for the first and third quarters of each fiscal year on Form
N-Q.  The  company's  Forms N-Q are  available  on the  Commission's  website at
http://www.sec.gov.  They may be reviewed and copied at the Commission's  Public
Reference  Room in  Washington  D.C.,  and  information  on the operation of the
Public Reference Room may be obtained by calling 1-800-SEC-0330.

      The net asset value per share at October  31,  2007 was  $12.00,  compared
with $12.17 at October 31, 2006.  Net  investment  income per share was $.19 for
the  six-month  period  ended  October  31,  2007,  compared  with  $.20 for the
six-month period ended October 31, 2006.

      At the company's last annual  meeting on June 19, 2007, the  reappointment
of Weiser LLP as the  company's  auditors  for the fiscal year ending  April 30,
2008 was ratified by the shareholders as follows:

         Shares Voted For                                2,774,276

      During the six-month period ended October 31, 2007, no director or officer
received  any  compensation  from the company  except for fees of $6,000 paid to
each director, plus an additional $2,500 to Paul Kramer as chairman of the audit
committee.  All  executive  officers  of the  company as a group  (two  persons)
received  compensation  (comprised  solely of said directors' fees)  aggregating
$12,000  during said period (which  excludes  professional  fees paid to the law
firm of which I. Robert Harris, secretary of the company, is a member).

      At its  meeting  on May 24,  2007,  the  Board  of  Directors  unanimously
approved the renewal of the company's  investment  advisory  agreement with J.P.
Morgan Investment Management Inc. for the period July 1, 2007 to June 30, 2008 .
The board  considered a variety of material factors and conclusions with respect
thereto that formed the basis for the board's approval, as discussed below.

      Throughout  the year,  the  directors  received and analyzed a substantial
quantity of comprehensive  information and written materials,  including ongoing
analysis of Tridan's existing portfolio and Morgan's recommendations in light of
its forecasts for the economy,  employment trends, business conditions,  federal
rate moves, interest trends including comparisons between tax-exempt and taxable
bonds,  appropriate  maturities,  quality,  yields,  diversification,  etc.  The
directors  subject  Morgan's  portfolio  management  to  scrutiny  at each board
meeting, including examination of transactions completed since the prior meeting
and an  overview  of the entire  portfolio.  Written  materials  received by the
directors  before and during each meeting include reports,  statistics,  charts,
graphs,  performance records,  comparisons with other funds and the like. Morgan
is   constantly   questioned   at  great  length   regarding   its  views,   its
recommendations and its performance.

      In addition to the foregoing,  as requested by Tridan's  corporate counsel
pursuant  to  Section  15(c)  of the  Investment  Company  Act of  1940,  Morgan
submitted its audited



Tridan Corp.
December 27, 2007
Page - 3 -


financial  statements  and detailed  information  regarding  Morgan's  business,
personnel and operations,  advisory services,  compensation  matters,  portfolio
strategy,  investment  performance,  sources of  information,  fee  comparisons,
compliance  programs,  and other  matters of  significance  to the  relationship
between Tridan and its investment  adviser,  all of which material was furnished
to each director.  The directors reviewed all of this material and discussed the
same at length, as well as their own views on Morgan's previous  performance and
relationship with Tridan, with particular attention to the following areas:

Investment Performance

      At each meeting,  the directors receive,  review and discuss with Morgan's
representatives   various  data  showing  Tridan's  portfolio   characteristics,
including market value,  average  duration,  credit quality,  coupon,  estimated
annual  income  and  yield  statistics,   and  breakdown  information  regarding
duration,  credit, and investment sectors.  Morgan's quarterly presentation also
includes the portfolio  performance  over three months,  year to date, one year,
three years, five years and ten years,  compared with the Lipper NY Intermediate
Muni Debt Funds, JPMorgan NY Tax Free Bond Fund, Sanford Bernstein NY Muni Fund,
and Lehman 1-17 Year NY Muni Bond Index.  Based on their  review,  the directors
all agreed that Tridan's relative investment performance has been satisfactory.

Nature, Extent and Quality of Service

      The  board's  analysis  of the  nature,  extent and  quality  of  Morgan's
services to Tridan was based on knowledge gained over time from discussions with
management  and at the board's  regular  meetings.  In addition,  the  directors
reviewed   materials   contained   in  Morgan's   response  to  Tridan's   15(c)
Questionnaire  pursuant to the Investment  Company Act of 1940, and its Form ADV
under  the  Investment  Advisers  Act  of  1940  concerning,  among  much  other
information, the qualifications,  education and experience of Morgan's personnel
involved in rendering those services.  As Tridan's  investment  adviser,  Morgan
manages the investment of the Company's assets, including purchases and sales of
securities,  and  arranges  for the  periodic  transfer of cash  required to pay
expenses and make  distributions to shareholders.  Morgan also provides clerical
and  bookkeeping  services,   and  prepares  and  issues  periodic  reports  and
statements.  Its affiliate maintains custody of Tridan's securities and provides
access thereto upon request.  The board considered its adviser's  performance of
these administrative and support services, including monitoring adherence to the
company's   investment   policies,   guidelines   and   restrictions,   Morgan's
responsiveness to requests by Tridan's counsel for periodic information, reports
and certifications required for compliance with securities laws and regulations,
and maintaining and monitoring their respective  compliance programs in light of
today's extensive regulatory requirements.  The board concluded that the nature,
extent



Tridan Corp.
December 27, 2007
Page - 4 -


and quality of the  services  provided  by Morgan to the  company  have been and
continue to be appropriate and beneficial.

Fees

      Under its Investment Advisory Agreement with Morgan, Tridan pays an annual
fee,  computed  and payable  quarterly,  equal to 0.28% of its net assets  under
management. The agreement requires Morgan to bear all expenses incurred by it in
connection with its activities  under the agreement,  without any  reimbursement
from the company. In addition, there is no charge made to Tridan for maintaining
custody of the company's securities and for custodial-related  services rendered
by Morgan and its affiliates.  In light of the nature, extent and quality of the
services  received  by Tridan  from  Morgan and its  affiliated  companies,  and
comparing the management fees charged by Morgan to other fixed-income investment
companies  managed by it, all of which are many times  larger than  Tridan,  the
Board considers Morgan's management fee to Tridan to be reasonable.

      After  full  consideration  of the  above  factors,  the  board  concluded
unanimously that renewal of the investment  advisory  agreement with J.P. Morgan
Investment  Management  Inc.  was  in  the  best  interest  of  Tridan  and  its
shareholders.

                                                      Sincerely

                                                      TRIDAN CORP.

To the Shareholders and Board of Directors
Tridan Corp.

We have  compiled the  accompanying  statements of assets and  liabilities,  and
schedules of investments in municipal  obligations of Tridan Corp. as of October

financial highlights (Note 6 to the financial statements) for each period in the
six months ended October 31, 2003 through 2007, in accordance with Statements on
Standards for Accounting and Review Services issued by the American Institute of
Certified Public Accountants.

A  compilation  is limited to  presenting  in the form of  financial  statements
information  that is the  representation  of management.  We have not audited or

Their report,  dated May 24, 2007, expressed an unqualified opinion thereon, but
they have not performed any auditing procedures since that date.

We are not independent with respect to Tridan Corp.

1.    Significant Accounting Policies

      The following is a summary of the significant  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. Investments are carried at
      amortized cost in the Company's accounting records but are shown at market
      value in the accompanying financial statements. Short-term investments are
      stated at cost, which is equivalent to market value.

      Fair values for the Company's  investments in municipal  obligations  have
      been determined based on the bid price of the obligation, if available; if
      not available,  such value is based on a yield matrix for similarly traded
      municipal  obligations.  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,
      which  quotations  were not readily  available  as of October 31, 2007 and
      2006.

      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;  however,  the Company is
      subject to minimum New York State and local franchise taxes.

      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.

                                                               October 31,

TRIDAN CORP.

NOTES TO FINANCIAL STATEMENTS
SIX MONTHS ENDED OCTOBER 31, 2007 AND 2006
- --------------------------------------------------------------------------------

1.    Significant Accounting Policies (continued)

      The  Company  maintains  all of  its  cash  and  cash  equivalents  in one
      financial institution. At times, such balances may be in excess of amounts
      insured by the Federal Deposit Insurance Corporation.

      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
      disclosure  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 when
      accounting  for  the  valuation  of  securities  and  the  realization  of
      investment.

                  and  procedures (as defined in Rule 30a-3(c)) as of the end of
                  the period covered by this report.  Based on that  evaluation,
                  said officers have concluded that the registrant's  disclosure
                  controls  and   procedures   are   effective  to  ensure  that
                  information  required  to  be  disclosed  in  this  report  is
                  recorded,  processed,   summarized  and  reported  within  the
                  required time periods.

            (b)   There was no change in the registrant's  internal control over
                  financial  reporting  that  occurred  during  its last  fiscal
                  half-year  that  has  materially  affected,  or is  reasonably
                  likely to materially affect, the registrant's internal control
                  over financial reporting.
