Three-zone thermal shock test chamber MTWC-3A
Model: MTWC-3A · Category: Test Chambers
Three-zone thermal shock test chamber MTWC-3A is equipped with a hot, cold and a central ambient temperature zone. The hot and cold air is sequentially directed into the ambient zone to provide the thermal shock. It provides a thermal shock range from (-65 °C to 150 °C ) used in the industrial sector to test for environmental adaptability.
