XQ-MHU-100DC Thermal Cycling Test Chamber 
I. Application Scope of the Cold and Hot Cycle Test Chamber; 
The high and low temperature alternating test chamber, also known as the constant temperature and humidity test chamber, can accurately simulate complex natural conditions such as low temperature, high temperature, high temperature and high humidity, low temperature and low humidity. It is suitable for quality inspection of electronic, electrical, batteries, plastics, food, paper products, vehicles, metals, chemicals, building materials, research institutes, inspection and quarantine bureaus, universities and other industry units. It complies with: GB/2423.1; GB/2423.2; GB/2423.3, GB/2423.4 testing standards. 
II. Standard for Cold and Hot Cycle Test Chamber; 
Can meet the following standards: GB2423.1-89 Low Temperature Test Method  GB2423.2-89 High Temperature Test Method  GB2423-93 Test D6 Alternating Wet Heat Test Method  IEC68-2-30 Test Method 
III. Features of the Cold and Hot Cycle Test Chamber; 
The balanced temperature and humidity control system (BTHC) uses the P.I.D. method to control the SSR, ensuring that the heating and humidifying capacity of the system is equal to the heat and moisture loss. Thus, it can be used stably for a long time.
