                     Registration Statement on Form S-3
                     ----------------------------------

Ladies and Gentlemen:

         We have acted as counsel to inTEST Corporation, a Delaware corporation
(the "Company"), in connection with the preparation of a Registration Statement
on Form S-3, as amended (the "Registration Statement"), filed with the
Securities and Exchange Commission under the Securities Act of 1933, as amended
(the "Act"), relating to the public offering of up to 2,000,000 shares of the
Company's common stock, par value $0.01 per share (the "Common Stock"), of which
1,000,000 shares of authorized but heretofore unissued shares of Common Stock
will be sold by the Company and 1,000,000 shares of Common Stock will be sold
severally by the selling stockholders named in the Registration Statement (the
"Selling Stockholders").

         We have assumed for the purposes of this opinion that an Underwriting
Agreement substantially in the form of that filed as Exhibit 1 to the
Registration Statement (the "Underwriting Agreement") has been duly executed and
delivered by the Company, the Selling Stockholders, Adams, Harkness & Hill, Inc.
and Janney Montgomery Scott, Inc. of the several underwriters named therein (the
"Underwriters"). The Registration Statement also relates to 300,000 shares of
Common Stock that may be sold by the Company pursuant to the Underwriters'
over-allotment option pursuant to the terms of the Underwriting Agreement.

         We have reviewed (a) the Registration Statement; (b) the Company's
Certificate of Incorporation and Bylaws; (c) certain records of the Company's
corporate proceedings as reflected in its minute and stock books; and (d) such
other documents and instruments as we have deemed necessary or appropriate for
purposes of this opinion. In our examination, we have assumed the genuineness of
all signatures, the authenticity of all documents submitted to us as originals
and the conformity with the original of all documents submitted to us as copies
thereof.






         Our opinion set forth below is limited to the General Corporation Law
of the State of Delaware.


         We are of the opinion that:

1.                The shares of Common Stock to be issued by the Company to the
                  Underwriters as described in the Registration Statement, when
                  and to the extent purchased by the Underwriters in accordance
                  with the Underwriting Agreement, will be legally issued, fully
                  paid and non-assessable; and

2.                The shares of Common Stock to be sold by the Selling
                  Stockholders to the Underwriters as described in the
                  Registration Statement have been legally issued and are fully
                  paid and non-assessable.

         We hereby consent to the use of this opinion as Exhibit 5 to the
Registration Statement. In giving such opinion, we do not thereby admit that we
are acting within the category of persons whose consent is required under
Section 7 of the Act or the rules or regulations of the Securities and Exchange
Commission thereunder.

         The opinion expressed herein is solely for your benefit, and may be
relied upon only by you.

                                          Very truly yours,



                                          /s/ Saul Ewing Remick & Saul LLP
