Vacuum meter leak detection method

The readings of some vacuum gauges are related to the types of gases, such as thermocouples and ionization vacuum gauges. Choosing appropriate gas or liquid as leakage material, these China Plasma Coating Machine suppliersvacuum gauges become detectors. Generally, there are vacuum gauges on the coating machine, which are very convenient to use and also a commonly used method of leak detection. Leakage indicators used in thermocouples include carbon dioxide, butane, alcohol and other thermocouples which react slowly and should be observed carefully. Leakage indicators for ionometers include helium, argon, alcohol, etc.
