V. Product Structure:

(1) The constant temperature and humidity test cabinet body is in the form of an integral structure. The refrigeration system is located in the lower rear part of the box, and the control system is located in the upper part of the test box.

(2) Within the air duct at one end of the studio, distributed heaters, refrigerating evaporators, fan blades, etc.; 试验50 cable holes are provided on the left side of the test box, and the test box is a single door (stainless steel insert door handle)

(3) Double-layer high-temperature and anti-aging silicone rubber seal can effectively guarantee the temperature of the test chamber.

(4) There are observation windows, frost protection devices and switchable control lights on the door. The observation window is made of multi-layered hollow tempered glass, and the inner bonded sheet type conductive film is heated and defrosted. The lighting adopts the imported brand Philips lamp tube, which can effectively observe the test changes in the working room.
