225L Stainless Steel Plate SUS304 Three Box Temperature Humidity Thermal Shock Test Chamber

Prodcut Introtation

Used widly in electron product industry,national defense industry,aviation industry.Can reduce a large number of test fee.Opearation easy,hig trust,is a reliable,high-performance test tool in labs.


1.high temperature groove,low temperature groove,test grove is static.

2.Shock way uses wind path changing methods,let high temperature and low temperature leading to test area,and reach the high-low temperature shock test goal.

3.Can set rotation times and defrost times.

4.Use touching colourful liquid controller,easy to operate,stable.

5.Temperature accuracy is high,use PID calculating methods.

6.Choose start-move place,high temperature and low temperature is rotation.

7.Showing test curve when operation.
