What is a Pirani vacuum gauge?

The Pirani gauge is one of the most used vacuum gauges, and one of the reasons is that it has a simple structure and is inexpensive. The type of vacuum gauge is one of the electric resistance type vacuum gauges, and when the stylus is installed in the measurement environment, the degree of vacuum is measured by the power flowing through the stylus according to the degree of vacuum. The Pirani gauge generally consists of a controller and a stylus, and the measurement range is about 0.5Pa to 2KPa. There is also a type in which the stylus and controller can be separated.

Application of Pirani vacuum gauge

The measurement range of the Pirani vacuum gauge is about 0.5Pa to 2KPa. This corresponds to the medium vacuum region and is often used for measurements in this region. This medium vacuum region is a vacuum state that can be reached using an oil rotary vacuum pump, and is used for measurement during measurement such as front gas suction. It is also used to create a vacuum state when conducting physics and chemistry experiments, and to measure vacuum vapor deposition, freeze-drying, medical equipment, analyzers, laser application equipment, vacuum exhaust equipment, vacuum packs for electron microscopes, etc.
