    2 Zone Thermal Shock Test Chamber

    Labtek 2 Zone Thermal Shock Test Chamber is designed to provide two opposite extreme temperature environments for temperature cycling and thermal shock testing of electronic components and assemblies to military specifications.

    Thermal shock testing is achieved by quickly and repeatedly transferring a specimen between a hot chamber and a cold chamber by means of an automatic carriage transport system. The hot chamber is on the upper side and the cold chamber is on the lower side.

    Touch screen programmable controller is produced in Korea.

    RS-485 communication interface, it can control / edit / record through computer.

    Chamber will shut down automatically in case of electrical power instabilities.
