Ozone inside the box passes through the specializedUse exhaust fans and ducts to exhaust to the outside;

control system

Programmable temperature and humidity controllerLCD touch controller, large LED display with high contrast and backlight function

The interface can be operated in both Chinese and English to display the set test parameters, running time, heater, and refrigeration compressor. It also has the functions of automatic test operation and PID parameter self-tuning.

The setting of parameters for system B adopts a human-machine dialogue method, only requiring the setting of temperature and humidity;The automatic operation function of the test box can be achieved.

The C system uses intelligent control software to automatically combine cooling, heating, and other system conditions,Thus ensuring high-precision control over the entire temperature range, achieving the goal of energy conservation and consumption reduction.

The detection device of D is capable of automatically displaying detailed faults and issuing alarms
