High Quality High and Low Temperature Constant Temperature Chamber

DY-WXM150 High and Low Temperature Constant Temperature Chamber

High and low temperature constant temperature chambers are mainly used to test the performance of materials in various environments and to test the heat resistance, cold resistance and dryness resistance of various materials. They are essential testing equipment in the fields of aviation, automobiles, home appliances, scientific research, etc. They are used to test and determine the parameters and performance of electrical, electronic and other products and materials after the temperature environment changes in high and low temperature constant tests. They comply with the JJF1101-2019 environmental test chamber temperature calibration specifications.
