Description
The gas piston pressure vacuum gauge is a high-accuracy pressure standard, which can verify the vacuum gauge and pressure gauge. High-purity nitrogen is used as the working medium. During the measurement process, the additional error introduced by the working medium becomes smaller due to the smaller viscosity, which further improves the sensitivity of the piston, making the output standard pressure value fluctuate less and have better repeatability.

Features
Using high-purity nitrogen as the working medium, during the measurement process, the additional error introduced is smaller due to the lower viscosity of the working medium, which further improves the sensitivity of the piston, making the output pressure value fluctuate less and repeatability better.
The material of piston rod and piston cylinder is tungsten carbide, which has the characteristics of high strength, high hardness and low temperature linear expansion coefficient, which improves the wear resistance of the piston and extends the life of the piston.
The rotation time of the piston is long, the friction force between the piston cylinder and the rod is small, and the output standard pressure value is more accurate.
With real-time display of system pressure, users can intuitively grasp the speed of boost and buck (optional function).
The change of the piston position is compared according to the graduation line, with the highest graduation line and the lowest graduation line.
The weight has been corrected for pressure deformation coefficient and local gravity acceleration.
All indicators are in full compliance with the national measurement verification regulations of JJG1086-2013 "Gas Piston Pressure Gauge" and JJG99-2006 "Weight", and each one can issue a "Verification Certificate".
