Product Description

252L Ess Test Chamber MIL STD Thermal Shock Test Chamber Water-Cooled Chamber

The product is designated to exam the endure capacity of the whole set equipment, components, spare parts and so on under the rapid changes in temperature. To know the effect to samples which caused by temperature change once or many times. The main parameters affecting the temperature change are high temperature and low temperature values, temperature rate, sample holding time in high or

low temperature , and the times of cycle.
