Wuhan constant temperature and humidity test chamber spot manufacturer characteristics:

1. The box door is equipped with an observation window, frost prevention device, and switchable lighting. The observation window adopts multi-layer hollow tempered glass, and the inner adhesive sheet conductive film is heated and defrosted. The lighting fixtures adopt imported brand Philips lamps, which can effectively observe the experimental changes in the studio;

2. Inside the air duct interlayer at one end of the studio, there are devices such as heaters, refrigeration evaporators, and fan blades distributed; On the left side of the test box, there is a Ø 50 cable hole, and the test box is a single door (stainless steel embedded door handle)

3. The double-layer high temperature and anti-aging silicone rubber seal can effectively ensure the temperature loss of the test chamber;

4. The box is in the form of an integral structure, with the refrigeration system located at the lower rear of the box and the control system located at the upper part of the test box;

5. Heater: Imported U-shaped heating tube;

6. Humidifier: Split humidification bucket humidification method;

7. Wind circulation system: special extended axis motor combined with multi blade wind turbine;

8. Refrigeration system: French Taikang Iron Armored Warrior fully enclosed compressor;
