Environmental Climate Horizontal Low Temperature Test Chamber
Environmental Test Chamber.pdf
Equipment summary:
Low temperature test chamber is used to test the material's property low-temperature, such as electrical, electronic products., as well as their original devices, The testing equipment is mainly made according to the national standard and user-defined requirements, it simulate the environment to test proformance of material as well as other relevant characteristics of physical at low temperature, Through testing to determine product performance whether it is still be able to meet the intended requirements.
Corresponding standard:
1.GB 10589-89 low temperature testing condition
2. GB/T5170.2-1996 basic parameters of environmental testing method for Electrical and electronic products,
3. GB2423.1-89 The basic test regulation for electrical and electronic products, Test A: low-temperature test method
Applicable industries :
Applied to test the prodcuts quality, such as electronic, plastic products, electrical appliances, instruments, food, vehicles, metals, chemicals, building materials, aerospace, medical care ... and so on.

Main Features:
1.Refrigerator adopts French original "Taikang" totally enclosed compressor.
2. Refrigeration system adopts unit or binary type low temperature circuit system design.
3. the use of multi-wing fan strong air circulation, to avoid any dead space, can make the test area temperature distribution evenly.
4.wind circulation out of the wind back to the design, wind pressure, wind speed are in line with the test standards, and can make the door open instant temperature back to stable time fast.
5. the box adopts horizontal, generous appearance, and large volume of the inner box.
6. The temperature control adopts imported touch button instrument, simple operation setting.
7. After the data and test conditions are input, the controller has a lock function to avoid changing the temperature value by human touch.
8. With P.I.D automatic calculation function, the temperature change conditions can be corrected immediately, so that the temperature control is more accurate and stable.
