Thermal Shock Test Cabinet
Function Description
Thermal shock test cabinet belongs to the same series as high and low temperature alternating humidity-heat test chamber and is an essential test device for aviation,automobile,household appliance,scientific research,etc. It’s applicable to tests and determination of parameters and property of electrical product,electronic product and others which have gone through high and low temperature,alternating humidity-heat degree and changes of converting environmental temperature in seconds.
Test chambers of the series have a wide adjustable control range over temperature and humidity,which meets national standard,GB/T 2423.1,2,3,4
<Test code of electrical and electronic product basic environment test A:low temperature test method;test B:high temperature test method;test Ca:constant humidity-heat test;test Db:alternating humidity-heat test>.
These kinds of chambers meets national standard,GB10592<technical conditions of high and low temperature test chamber> and <technical conditions humidity-heat test chamber>.
