【产品描述】Thermal vacuum test is a test to verify the performance and function of spacecraft and its components under vacuum and certain temperature conditions. It consists of cold immersion, hot immersion and variable temperature process. Thermal vacuum tests can be carried out on components, subsystems and satellites as a whole. In the simulation test, most of the specimens are in working state and their working parameters and environmental parameters are measured. The test conditions can be formulated according to the user's requirements.
