High and low temperature thermal shock test box, three box temperature cycling shock box

Application of Cold and Hot Shock Test Chamber Suitable for adaptability testing of electronic, electrical, and other product equipment under rapidly changing ambient temperature conditions, and also an assistant for screening initial failures of electronic components.

1Divided into three parts: high temperature zone, low temperature zone, and testing zone, the test sample is placed completely stationary in the testing zone. A unique heat storage and cold storage structure is used, and the forced cold and hot air path switching method is introduced into the testing zone to complete the cold and hot temperature shock test; It can be used as both a thermal shock test chamber and a separate high-temperature or low-temperature chamber;
