Introduction to High and Low Temperature Impact Test Chamber R: This test chamber is suitable for assessing the ability of products (whole machines), components, parts, etc. to withstand rapid temperature changes. This temperature impact test can understand the impact of temperature changes on the test sample once or continuously multiple times. The main parameters that affect the temperature change test are the high and low temperature values within the temperature change range, the holding time of the sample at high and low temperatures, and the number of cycles of the test.
