HSLQ Gas Piston Pressure Gauge
Product Description
The HSLQ gas piston pressure gauge is a high-accuracy pressure standard. It uses high-purity nitrogen as the working medium.
During the measurement process, because the viscosity of the working medium is lower, the additional error introduced is smaller, further improving the sensitivity of the piston, making the fluctuation of the output pressure value smaller and the repeatability better. At the same time, it is more convenient to calibrate oil-free instruments.

Product Details
Product Overview
The HSLQ gas piston pressure gauge is a high-accuracy pressure standard. Using high-purity nitrogen as the working medium, during the measurement process, the additional error introduced due to the reduced viscosity of the working medium is smaller, further improving the sensitivity of the piston, making the fluctuation of the output pressure value smaller and the repeatability better. At the same time, it is more convenient to verify oil-free instruments.

Product Features
lUsing high-purity nitrogen as the working medium, during the measurement process, because the viscosity of the working medium becomes smaller, the additional error introduced is smaller, further improving the sensitivity of the piston, making the fluctuation of the output pressure value smaller and the repeatability better.
lThe piston rod and piston cylinder are made of tungsten carbide, which has the characteristics of high strength, high hardness, and low coefficient of linear expansion with temperature, improving the wear resistance of the piston and extending its service life.
lThe piston has a long rotation time, and the friction between the piston cylinder and rod is small, making the output pressure value more accurate.
lReal-time display of system pressure, allowing users to intuitively grasp the pressurization and depressurization speed (optional function).
lThe change in piston working position is displayed via LCD, making observation more intuitive.
lAdopts a hanging basket structure with a low center of gravity and good stability.
lThe weights have been corrected for pressure deformation coefficient and local gravitational acceleration.
lAll indicators fully comply withJJG1086-2013 "Gas Piston Gauge",JJG99-2006 "Weights" national metrological verification regulations, each unit can issue a "Verification Certificate".
