application
This test chamber provides environments of high temperature, low temperature, high humidity, and low humidity to compare the material changes and strength attenuation of rubber, plastic, electronic products, and other materials before and after testing. This machine can also simulate the container environment to detect the fading and shrinkage of rubber and plastic under high temperature and humidity. This machine is specifically designed to test the heat resistance, cold resistance, dry resistance, and moisture resistance of various materials.

Two box constant temperature and humidity test chamberBy controlling the heating system, cooling system, humidification system, dehumidification system and other parts accurately through the control system, the temperature and humidity inside the test chamber can be adjusted. During the experiment, the product to be tested is placed inside the test chamber, and the required temperature and humidity conditions are set through the control system to make the temperature and humidity inside the test chamber change according to the set values. During the experiment, the control system will monitor the temperature and humidity inside the test chamber in real time and adjust them according to the set values to ensure that the temperature and humidity inside the test chamber remain within the set range.
Structure
It mainly consists of a box, a control system, a heating system, a cooling system, a humidification system, a dehumidification system, an air duct system, and other parts. The box is made of high-quality materials and has good insulation and sealing properties. The control system adopts advanced microcomputer control technology to achieve precise control of parameters such as temperature, humidity, and time in the test chamber. The heating system adopts electric heating method to provide a constant high temperature environment. The refrigeration system adopts a compressor refrigeration method to provide a constant low-temperature environment. The humidification system adopts ultrasonic humidification method to provide a constant high humidity environment. The dehumidification system adopts a compressor dehumidification method to provide a constant low humidity environment. The air duct system adopts centrifugal fans and air duct design to ensure uniform distribution of temperature and humidity inside the test chamber.
