The thermal vacuum test chamber is a testing device that simulates the space environment or extreme low-pressure, high-temperature/low-temperature conditions. It is mainly used in the fields of aerospace, electronic components, and materials science, to verify the reliability of products in the vacuum + temperature alternating environment.
