Mainly composed of control panel, vertical distribution cabinet, moisturizing storehouse board, air supply fan, heater, humidifier and refrigeration unit, it is aimed at high performance electronic products (e.g. computer whole machine, display, computer terminal, power supply, main board, automobile parts, etc.) to improve product stability. Important experimental equipment for reliability is an important production process for enterprises to improve product quality and competitiveness.
The environmental test chamber can accurately simulate complex natural environments such as low temperature, high temperature, high temperature and high humidity, low temperature and low humidity, etc. It is suitable for product reliability testing in various industries such as plastics, electronics, food, clothing, vehicles, metals, chemicals, and building materials.
1. Reinforcement of square steel frame structure, solid assembling of high-strength coloured steel warehouse plate, high temperature spraying of double-sided electrostatic resin on external cold-binding plate, sealing welding of SUS# heat-resistant and cold-resistant stainless steel inner box, insulating layer using fire-resistant environmental protection glass fiber cotton insulation material, refrigeration system importing advanced energy-saving refrigeration from Japan and Germany. Technology, higher efficiency, better stability, longer operating life, more than 20-50% energy saving than traditional equipment, control system and control circuits are imported well-known brand parts.

The base of the walk-in constant temperature and humidity test chamber is made of 8# channel steel welded into a mesh frame so that it can bear the weight of the chamber and personnel test pieces under horizontal conditions without causing unevenness and cracking on the bottom of the chamber. . The bearing capacity is 200kg/square meter. The chamber body (the main body of the test chamber (shell)) is divided into six chamber surfaces and a double-open chamber door. The size is 1800×2000 mm. The chamber body material is a high-quality stainless steel plate with an inner liner. (To prevent the inner wall from rusting under humid operation for a long time), the outer tank is made of high-quality color steel plate (domestic famous brand), and the insulation medium is polyurethane hard foam insulation, which is light and resistant to impact, and has good thermal insulation performance. The door material of the constant temperature and humidity test chamber is also made of color steel plate, and the door handle is open-type inside and outside, so that the test personnel can freely open the door from the closed room.
