[inTEST News Release Letterhead]

CHERRY HILL, NJ, May 12, 2010 - inTEST Corporation (Nasdaq: INTT), an independent designer, manufacturer and marketer of semiconductor automatic test equipment (ATE) interface solutions and temperature management products, today announced results for the quarter ended March 31, 2010.

Net revenues for the quarter ended March 31, 2010 were $9.5 million, compared to $8.4 million for the fourth quarter of 2009. Net income for the quarter ended March 31, 2010 was $1.1 million or $0.11 per diluted share, compared to $142,000 or $0.01 per diluted share for the fourth quarter of 2009. The net income for the fourth quarter included restructuring charges of $307,000 or $0.03 per diluted share, which represented one-time termination benefits and facility closure costs related to the relocation of our Sigma Systems subsidiary.

Robert E. Matthiessen, President and Chief Executive Officer of inTEST, commented, "The sequential and year-over-year improvements we achieved in revenue, gross margin and profitability underscore the success of our business strategy. We are benefitting from the considerable operating leverage we achieved in our business as the broader semiconductor market rebound continues. Importantly, at the same time, our results reflect our successful diversification into non-semiconductor, non-traditional markets. We now count as customers some of the world's best known companies in the military/aerospace, industrial and telecommunications industries. We are gaining momentum as manufacturers are increasingly required to verify that their products operate at set temperatures. We are also excited about significant growth opportunities in electronic sensors, whose small size is suited for being conditioned for testing by inTEST's ThermoStreams and Thermal Platforms, as well as opportunities in the microwave market in Asia and Europe, which would build on our leadership in the U.S. market."

Hugh T. Regan, Jr., Treasurer and Chief Financial Officer noted, "Bookings for the quarter ended March 31, 2010 were $14.0 million, an increase of 49% over the $9.4 million in bookings for the fourth quarter of 2009. We remain focused on controlling all operating expenses, while continuing to provide customers with the high-quality and support they have come to rely on inTEST for. We do, however, expect modest increases in expenses in the second quarter as we support key growth initiatives, including some strategic R&D investments and selected headcount additions as we meet higher customer demand levels."

Financial Outlook:

The Company expects continued improvements in net revenues and net income in the second quarter ending June 30, 2010 on both a sequential and year-over-year basis. The above outlook is based on the Company's current views with respect to operating and market conditions and customers' forecasts, which are subject to change.
