inTEST Corporation supplies test and process solutions for use in manufacturing and testing in automotive, defense/aerospace, industrial, life sciences, security, and semiconductor markets worldwide.

The company operates through two segments, Thermal Products (Thermal) and Electromechanical Semiconductor Products (EMS).

The Thermal segment offers ThermoStream products that are used in the semi market as a stand-alone temperature management tool, or in various electronic test applications; Thermal Chambers; Thermal Platforms; Thermonics temperature conditioning products that provide tempered gas or fluid; ultra-cold storage solutions, including biomedical freezers, refrigerators, and mobile storage solutions; EKOHEAT and EASYHEAT induction heating systems; and digital streaming and image capturing solutions.

The EMS segment provides in2, Cobal, and LS series manipulators that hold various test heads and enable an operator to reposition a test head for alternate use with various probers or handlers on a test floor; and docking hardware products, which protect the interface contacts and ensure proper repeatable and precise alignment between the test head's interface board and the prober's probing assembly or the handler's test socket.

This segment also offers tester interfaces that provide electrical connections between the tester and the wafer prober or integrated circuit (IC) handler; and scorpion flying probe test systems, which designs and manufactures robotics-based electronic test equipment, as well as provides application support services.

Its products are used in production testing of wafers and specialized packaged ICs in back-end testing by semiconductor manufacturers.

The company markets and sells its products to semiconductor manufacturers, third-party foundries, test and assembly providers, and original equipment manufacturers. inTEST Corporation was incorporated in 1981 and is headquartered in Mount Laurel, New Jersey.
