Desktop High And Low Temperature Test Chamber

Desktop High And Low Temperature Test Chamber

This constant temperature and humidity environment test chamber can simulate various temperature and humidity environments, suitable for testing electronic, electrical, food, automotive, rubber, plastic rubber, metal and other products, meeting the reliability and stability performance parameters of various harsh environments such as GB/T2423 and GJB150A1/4, and will provide you with a basis for predicting and improving product quality and reliability.
Technical features:
1. Adopting a 7-inch TEMI880 color touch screen display, the screen is intuitive and easy to operate, with permanent historical data saving function
2. Pre order power on/off function, end planning settings, automatically save data curves during power outages, etc
3. At the end of the experiment, the test sample will automatically return to room temperature to avoid frost and condensation protection mechanism
4. Adopting servo refrigerant flow control technology effectively achieves energy savings of over 30%
5. The experiment is conducted in a loop without affecting the impact time
6. Using pure aluminum finned evaporator, effectively reducing energy storage time and saving energy

Meet the standards:

The performance indicators comply with the requirements of GB5170, 2, 3, 5, 6-95 "Basic Parameter Calibration Methods for Environmental Testing - High Temperature, Constant Damp Heat, and Alternating Damp Heat Test Equipment". Environmental Test Regulations Test B: High Temperature Test Method GB2423.2-89 (IEC68-2-2) Environmental Test Regulations Test Ca: Constant Damp Heat Test Method GB/T2423.3-93 (IEC68-2-3) Environmental Test Regulations Test Da: Alternating Damp Heat Test Method GB/T423.4-93 (IEC68-2-30)

Heating system:

Continuous PID regulation, using AC contactors as heating actuators, safe and reliable, with a separate over temperature protection system.
Air duct system:

To ensure a high uniformity index, the test chamber is equipped with an internal circulating air supply system; Inside the air duct interlayer at one end of the studio, there are devices such as heaters, refrigeration evaporators, and fan blades distributed; Use a fan to circulate the air in the box. When the fan rotates at high speed, the air in the working chamber is sucked into the air duct from the lower part. After heating and cooling, it is blown out from the upper part of the air duct. The air that exchanges heat with the test sample in the working chamber is then sucked into the air duct and repeatedly circulated to meet the temperature setting requirements.
