Environmental Stress Chamber

Name: Environmental Stress Chamber
Brand: Xi'an LIB Environmental Simulation Industry

The environmental stress chamber is used to test the performance and reliability of products in different temperature and humidity environments, and help determine the degree of tolerance of products in the actual use environment.

With a temperature control range of -70 ° C to 150 ° C, it accurately simulates extreme cold and extreme heat. Humidity control parameters range from 10% to 98% RH, which fully covers all humidity conditions from dry to high humidity.

Model: TH-100C, TH-225C, TH-500C, TH-800C, TH-1000C

Standard: AAMA501, ASTM D4169-16, IEC 61215, IEC 61646, IEC61108, IEC62688, MIL-STD-812D

Configuration of Environmental Stress Chamber

① Workroom	SUS 304 Mirror stainless steel, high and low temperature resistance, corrosion resistance, easy to clean, Double punch design sample holder, promote air circulation, height adjustable. Test cable on the left side to energize the test piece and restore the most realistic usage.
② Air circulation system	Composed of fans and air ducts, the fans promote the continuous circulation of air in the chamber, so that the temperature and humidity can be evenly distributed to avoid excessive differences in local temperature and humidity.
③ Heating system	The heating wire is used to raise the temperature in the chamber to the set value by converting electrical energy into heat energy, and the power configuration can be performed according to different heating rate requirements.
④ Cooling system	It is mainly composed of a compressor, a condenser, a throttling device (capillary) and an evaporator to form a refrigeration cycle.
⑤ Humidity system	Increase the humidity of the air inside the chamber so that it reaches the set humidity level.
⑥ Control system	According to the difference between the set value and the feedback value, the controller accurately regulates the operation of heating, cooling, humidification, dehumidification and other devices to achieve accurate control of temperature and humidity.
