Single Open Left Hinge Right Handle 64L Stainless Steel 3-Zone Environmental Test Chamber
Stainless steel with a protective device 500L 2-zone thermal shock chamber
Working Principle
This is so called three-zone type thermal shock test chamber.
Sample is placed in the test chamber, more extreme temperature than test temperature can be set in
high-temperature chamber and low-temperature chamber. When it comes to low temperature test, cold
chamber door open, and low-temperature chamber working together with test chamber.
When converted into high-temperature test, cold chamber door closed, hot chamber door are opened,
and test chamber working together with high-temperature chamber.
Conversion of mechanical action (transferring from high temperature to low temperature or low
temperature to high temperature) can be completed in less than 1second, and the temperature can be
quickly stabilized.
During the whole test, test sample is no need to be moved, and without any human intervention.
