Type resistance vacuum gauge
This type of regulation uses a stabilized hot wire with extremely small heat capacity as the vacuum sensitive element, and has automatic ambient temperature compensation and dust protection functions. It has a wide range, fast response, anti-pollution, oxidation resistance, and small drift. Long life, stable performance and other characteristics. Especially suitable for rough and low vacuum measurement.
