Did you think that getting a thermal shock chamber was too expensive, required special utilities, and half your lab-space? The JQTS-2-225 thermal shock chamber is the solution. It transfers product loads between cold and hot zones with a temperature range of -65°C to 200°C.

Meets strict Mil-Std 883 1010.7/1010.8 thermal cycling requirements with 4 kg. (8 lbs.)
Also can be used for IEC 61300-2-47, JEDEC JESD47E, JESD22-A104, and others
Touch-screen operation is very easy, yet full-featured
The cold zone is cooled by refrigeration. No need for tanks of liquid nitrogen (or cooling water supply)
The only utility required is 208V power
Super quiet operation of less than 60dB
