This device is divided into three parts: high temperature zone, low temperature zone, and testing zone. It adopts a unique thermal insulation and heat storage effect, and uses a cold and hot air path switching method to introduce the test sample for cold and hot shock testing.

Adopting the original Japanese made large LCD (320X240dots) display control system in both Chinese and English.

High program memory capacity, can be set to store 100 sets of programs, * large cycle setting 9999 cycles, each time period * large setting 9999 Hrs 59 Mins

Equipped with an RS-232C communication interface device, it can be connected to a computer for control, editing, recording, and ten dynamic connections (TIMER SINGAL RELAY). Use this key. When performing cold and hot shock conditions, the function of Zone 2 or Zone 3 can be selected.

Equipped with a fully automatic, high-precision system, any mechanical action is completely locked and processed by P.L.C.

When there is a mechanical failure, it is equipped with an automatic circuit and warning signal. If the input power is unstable, it has an emergency stop device.
