1、 Product Introduction:< The constant temperature and humidity testing machine, also known as the environmental testing machine, tests the heat resistance, cold resistance, dry resistance, and moisture resistance of various materials. Suitable for quality testing of electronic, electrical, communication, instrument, vehicle, plastic products, metal, food, chemical, building materials, medical, aerospace and other products< 2. Product Features:

High quality appearance, the body adopts a circular arc shape, the surface is treated with matte stripes, and a flat non reactive handle is used, which is easy to operate, safe and reliable.

The rectangular laminated glass observation window can be used for observing the test sample during the experiment. The window is equipped with an anti sweat electric heater device to prevent water vapor condensation and droplets, and a high brightness PL fluorescent lamp to maintain illumination inside the box.

The double-layer isolation and airtight tightness of the box door can effectively isolate internal temperature leakage.

Equipped with an external water supply system, it is convenient to supplement the humidification tank water supply and automatically recycle it for use.

The compressor circulation system adopts the French "; Taikang "; The brand can effectively remove lubricating oil between the condenser and capillary tubes, and the entire series uses environmentally friendly refrigerants (R23, R404, R507).

The controller adopts an imported LCD display screen, which can simultaneously display measured values, set values, and time. The controller has multi-stage program editing and can be used for fast (OUICK) or slope (SLOP) control of temperature and humidity.

The built-in mobile pulley is easy to move and place, and has strong positioning screws to fix the position.
