Product Description
Description
Piston pressure gauge is a high-accuracy pressure standard. It is a measuring instrument that uses the principle of hydrostatic balance (that is, the fluid pressure acting on the effective area of the piston is balanced with the gravity of the load). And generally it consists of a piston system, special weights, and pressure calibrator.

Features
1.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.
2. The change of the working position of piston adopts the liquid crystal display, and the observation is more intuitive.
3. With real-time display of system pressure, users can intuitively grasp the speed of boost and buck (optional function).
4. The piston system is of modular design, and the module can be unscrewed directly when it is sent for inspection, without carrying a heavy mainframe.
5. The piston has a sewage system, and oil containing impurities in the oil cup can be directly discharged through the sewage port.
6. The special structure design of the pressurization system saves effort when pressurized.
7. Using aerospace-grade sealing materials, long-term reliable and no leakage.
8. The high-pressure piston weight adopts the hanging basket structure, with low center of gravity and good stability.
9. Using a quick pressure connector, it is easy to disassemble and install the inspected meter.
10. All indicators are in full compliance with the national measurement verification regulations, (JJG59-2007 "Piston Pressure Gauge" and JJG99-2006 "Weight") and each one can issue a "Verification Certificate"
