- Stuthings PMG series Pirani vacuum gauge is a vacuum gauge with high vacuum measurement and high repeatability.
Used for vacuum pressure measurement in high, medium and low vacuum environments.
Ultra-wide measurement range is achieved based on two independent MEMS Pirani sensors. It also has full-scale temperature compensation function.
It is not sensitive to the installation position and can be installed at will.
The built-in thermally recoverable fuse can effectively prevent electrical interface misconnection and reverse connection from damaging circuit components.
Optional RS485 digital communication interface and analog interface.
