Liquid Nitrogen Thermal Shock Test Chamber

Application:

Liquid nitrogen cooling and heat shock test chamber is suitable for electronic elements of safety performance test screening tests provide reliability test, products, etc., at the same time, through this equipment test, can improve the reliability of products and product quality control.

 Box structure:

Hot and cold impact test box all functions controlled by computer, is a self-developed software, has the good interface, the user's operation and monitoring is more simple and intuitive, maintain function will keep you running applications in the present condition, can temporarily change the program of numerical, time parameters can be set on the screen, the refrigeration, heating and blue transfer switch, according to the set value automatically.

Independent control of cold box and hot box.

The liquid cabinet adopts vacuum heat preservation to ensure no leakage.

The product insulation effect can be fully guaranteed.

The test box door and the circulating fan, the blue transmission and other interlocks, protect the safety of the operator, once the door is opened, the circulation fan and the blue transmission power supply will be automatically cut off.
