Thermal Shock Chamber/Hot Cold Temperature Shock Chamber 

Scope of application

This series of cold and heat shock test box is suitable for alternating shock test of electrical and electronic products and electronic parts.

Applicable standards

Products can meet CNS, MIL, IEC, JIS, GB/T2423.5-1995, GJB150.5-87 and other standards

Control mode of cold and hot impact test chamber:

The low temperature and high temperature storage tank is used to open the valve according to the action, and the low temperature and high temperature are quickly sent to the test tank through the air supply system, so as to achieve the rapid temperature impact effect, balance the temperature control system (BTC) + specially designed air supply circulation system, P.I.D.SSR is controlled in such a way that the heat added to the system is equal to the heat loss, so that it can be used stably for a long time.
