This thermal stress rapid change test chamber is designed to evaluate the ability of complete equipment, components, and parts to withstand rapid temperature fluctuations. This thermal shock test reveals the effects on test samples resulting from single or repeated exposure to temperature changes. The main parameters affecting the temperature change test include the high and low temperature values defining the temperature range, the dwell time of the sample at high and low temperatures, and the number of test cycles.
This test chamber is intended for testing non-heat-dissipating samples and low-heat-dissipating samples. For heat-dissipating samples, the heat dissipation power must not exceed the temperature control cooling capacity of the chamber’s refrigeration system; exceeding this limit will affect the chamber’s temperature transition speed and performance. It is recommended that heat dissipation of the test sample be less than 300 W. If you have special requirements, our company offers customized solutions.
