Thermal Vacuum Test Chamber

The thermal vacuum test chamber can simulate a certain degree of space vacuum conditions, but cannot fully simulate the real space environment. Vacuum in space refers to the environment in which there is no air or atmospheric pressure, while a thermal vacuum test chamber can only provide conditions of low pressure or near vacuum.

The thermal vacuum test chamber simulates the vacuum environment in space by reducing gas pressure. It will use an exhaust system to exhaust the gas inside the test chamber, thereby reducing gas pressure. This operation can simulate the low-pressure environment in space, allowing technology products to be tested at lower atmospheric pressures.
