Three Boxes of Hot And Cold Shock Test Box

The three-zones hot and cold shock test chamber is a test chamber used to simulate the hot and cold shock of products in different temperature environments. It is mainly used for high and low temperature shock tests of complete machines and parts of products in the fields of aviation, aerospace, military industry, ships, electrical engineering, electronics, etc., as well as storage and testing in high or low temperature environments.

Precise temperature control: can accurately control the temperature of high temperature box, low temperature box and test box, with small temperature fluctuation, generally can be controlled within ±1℃.
Fast impact speed: can achieve rapid switching of high and low temperature in a short time, the damper mechanism switching time does not exceed 10 seconds, and the hot and cold impact temperature recovery time does not exceed 5 minutes.
Easy operation: using a large color LCD human-machine touch dialogue LCD human-machine interface controller, simple operation, easy to learn, support Chinese and English display, with 96 test specifications independent setting capabilities.
High safety performance: with power overload protection, leakage protection, control circuit overload, short circuit protection, compressor protection, grounding protection, over-temperature protection and other powerful safety protection functions.
