Introduction
This type of gauge adopts stable heat treated hot filament that has tiny heat capacity as the vacuum sensor. It also has the function of automatic temperature compensation and dust protection. The gauge has the advantages of wide range, fast response, anti-pollution, oxidation resistance, small drift, long service life, stable performance and so on. Therefore, it is particularly suitable for rough and low vacuum measurements.
