Product Description: Gas piston pressure gauges are high-accuracy pressure standards that use gas as the working medium. They can measure and calibrate gauge pressure, absolute pressure, and vacuum pressure (negative pressure). The piston pressure gauge system is made of tungsten carbide, ensuring the piston is rust-resistant, wear-resistant, and has a long service life. Compared to piston pressure gauges using liquids as the working medium, gas piston pressure gauges have a
