    The measuring appliance is equipped with an advanced LCD touch screen, which can provide multiple procedure setting in both Chinese and English versions. The adoption of dialogue box Mac OS in programming can make the operation precise and quick, and the cooling system can run automatically as long as you pre-set the temperature. The measuring device can display the malfunctions in detail and make record of them, which enable you to correct the problems as quickly as possible.
Furthermore, the device has the timing function which can automate or stop running at any time.

    This test chamber can satisfy GB10592-89 “Technical conditions for high & low temperature test chambers”, and GB10586-89 “Technical conditions for interchanging test chambers”.

Adopting the standard of sense organ:

    The sense organ is used to test the temperature & humidity, which saves the needs of using gauze to maintain it. It avoids the effect of unqualified water since no water is needed in the RH testing process. The independent use of humidifier and purifier simplifies the structure. The distillation purifier in the standard installationt can supply purified water directly, which increases the reliability of device.

Profile of the product series:
    Controlling mode: balanced temperature/humidity control mode
    Refrigeration mode: Unipolar refrigeration (air swept type); and bipolar compound refrigeration (air swept type)
    Humidifying mode: the galvanothermy mode of vapor generation
