It can be used in the temperature shock test and fast-changing temperature test in a wide range such as aviation, air space, electronic components and material research. The High and Low Temperature Thermal Shock Chamber consists of three separate chambers: high temperature chamber, low temperature chamber and test chamber.

Operation Principles
The specimen is placed in test chamber specimen which cannot be placed in high temperature chamber or low temperature chamber. High temperature chamber pre-heats the air and low temperature air chamber pre-cools the air. When doing the test of temperature changing from high to low, the low temperature chamber will blow the pre-cooled air to the test chamber. Then, the air in test chamber will reach your target temperature in several minutes (“recover time”). When doing the test of temperature changing from low to high, the high temperature chamber will blow the pre-heated air to the test chamber. Then the air in test chamber will reach your target temperature within the recover time.
