1. High and low temperature and low pressure test chamber Composition of the vacuum system: The vacuum system is a component for obtaining vacuum degree and measuring and controlling vacuum degree, and consists of a vacuum measuring system and a vacuum obtaining unit

2. Vacuum degree measurement: The vacuum degree is measured by a pressure sensor. The vacuum gauge uses pressure strain to achieve vacuum degree measurement. The measurement data is a linear electrical signal, which can be directly input to the device controller for display and control.
