Applications
The gas piston pressure gauge is a high-accuracy pressure standard instrument that uses gas as the working medium. It can measure and calibrate gauge pressure, absolute pressure, and vacuum pressure (negative pressure).The piston system of the gas piston pressure gauge is made of tungsten carbide, which ensures the piston is rust-proof, wear-resistant, and has a long service life. Compared with piston pressure gauges that use liquid as the working medium, the gas piston pressure gauge—due to the difference in working medium—features a longer piston rotation duration, higher sensitivity, better repeatability, and accurate and reliable measurement data.
