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. .
The walk-in constant temperature and humidity test chamber is suitable for testing various performance indicators of aerospace products, information electronic instruments, materials, electrical engineering, electronic products, and various electronic components in high and low temperature or hot and humid environments.

High intelligence: According to the test conditions and requirements, automatic control reaches the set value with the maximum capacity and maintains the set value with the minimum capacity to achieve the best overall control.

High reliability: reasonable structure, easy installation, automatic fault recovery function, and easy maintenance.
Consumption and energy saving: heating and humidification work alternately, multi-circuit throttling thermal expansion refrigeration circuit.
Special design: Targeted design can be carried out according to customer needs, and the internal dimensions and performance indicators of the box can be changed. 1. GB/T2423.1-2001 low temperature test method;

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.
