High and Low Temperature Thermal Shock Chamber

Specifications

High and Low Temperature Thermal Shock Chamber 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.

HLST-500D has two separate chambers: high temperature chamber and low temperature chamber.
HLST-500T has three separate chambers: high temperature chamber, low temperature chamber and test chamber.

Operation Principles:
HLST-500D: The sample moves back and forth between the high temperature chamber and the low temperature chamber automatically during the measurement.
HLST-500T: The sample always stays in the test chamber during the measurement. High temperature chamber prepares high temperature air and low temperature chamber prepares low temperature air. The sample chamber will connect with high temperature chamber for high temperature test and will connect with low temperature chamber for low temperature test. Then, the air in test chamber will reach your target temperature in several minutes (“recover time”).
