Free home delivery, installation and debugging operation introduction, and machine operation technical training. (Until the demand side employees operate independently and are satisfied).

This product complies with standards such as GB/T2423.1.2 GB10592-89 GJB150.

Instructions for Cold and Hot Shock Test ChamberThe equipment adopts a modular structure, consisting of a high-temperature test chamber located at the upper part, a low-temperature test box located at the lower part, a refrigeration unit cabinet located at the rear, and an electrical control cabinet (system) located on the left rear panel This method has a small footprint, compact structure, and beautiful appearance. The refrigeration unit is placed in an independent unit box to reduce the impact of vibration and noise during the operation of the refrigeration unit on the test box.

*Temperature and humidity controller, with simple operation, easy learning, high control accuracy, * PID mode, can save energy by more than 10%.

It can independently set three different conditions: high temperature, low temperature, and thermal shock, and has the function of a high and low temperature testing machine.

The number of cycles and defrosting times can be set for automatic (manual) defrosting The air outlet is detected and controlled by the return air outlet sensor, and the switching time of the air door mechanism is completed within 10 seconds.

Equipped with fully automatic, high-precision system circuits, any component action, * with P.L.C locking processing, all using P.I.D automatic calculation control.

The temperature recovery time is completed within 5 minutes.

When an abnormal situation occurs during operation, the screen will automatically display the cause of the fault, and an emergency stop device will be installed when unstable input power is detected.

Optional USB interface for convenient storage, with standard RS-232 or RS-485 computer communication interfaces available. Implement remote control.

The frequency of application of cold and hot shock test chambers in verifying and improving the environmental adaptability of equipment is second only to vibration and high and low temperature tests. It is used to assess the adaptability of products to rapid changes in ambient temperature, and is a test in equipment design and batch production stages. In some cases, it can also be used for environmental stress screening tests
