Product usage:

Thermal shock environmental test chamber is used to test the material structure or composite materials, in an instant by the very high temperature and very low temperature can withstand the extent of continuous environment in order to test in the shortest time of its thermal expansion and contraction caused by chemical changes or physical hurt.

thermal shock environmental test chamber  be equipped with a PID auto calculation control,safety device.so shermal shock chamber can program control the change tempereture of hot chamber and cool chamber during cycles testing.

that means this thermal shock environmental test chamber can test the material's chemical change or physics change by expansion and contraction within short time.and tis type environmental testing chamebr can application to metal, plastic, rubber, electronic etc materials and can be used for product improvement's reference.
