Description High Accuracy Gas Piston pressure calibrator gas Piston Manometer
With the development of the domestic measurement industry, the original gas-medium oil-lubricated vacuum piston pressure has gradually withdrawn from the stage of history, and has been replaced by a gas piston pressure gauge. The pressure of the pure gas piston pressure gauge is stable and reliable, which greatly improves the The sensitivity and uncertainty of piston pressure gauges provide the perfect standard instrument for high-precision metrology.
Features High Accuracy Gas Piston pressure calibrator gas Piston Manometer
1. The piston system is made of tungsten carbide, which is wear-resistant, has a small temperature drift coefficient and has a long service life.
2. Pressure range -100KPa~600KPa optional
3. Meet the JJG1086-2013 "Regulations for the Verification of Gas Piston Pressure Gauge" to distinguish the traditional oil lubricated gas piston pressure gauge.
4. The pressure interface is a quick interface, which is convenient and quick.
5. The valve adopts a unique design, which is convenient for pressure regulation.
6. Optional temperature, pressure, drop digital indicating system, convenient and quick.
7. Positive and negative pressure switching, convenient and quick.
8. Measurement range: The nominal nominal measurement range is consistent with the actual measurement range.
9. The piston system can be easily taken out for inspection (no need to carry a heavy mainframe)
10. It can be used as a calibration piston pressure gauge for transmission; it can also be used for high-precision testing. Can be equipped with kg weight and MPa weight.
11. Advanced pressurization system, light and durable!
12. The weight adopts a hanging basket structure, with a low center of gravity and excellent stability.
13. Each unit is issued with the "Verification Certificate" of the Northwest Institute of Metrology and Testing

Funcation High Accuracy Gas Piston pressure calibrator gas Piston Manometer
The gas piston manometer is a high-accuracy pressure standard. It uses gas as the working medium to measure and calibrate gauge pressure, absolute pressure, vacuum pressure (negative pressure), etc. The piston gauge system is made of tungsten carbide. So as to ensure that the piston has the characteristics of non-rust, wear resistance and long service life. Compared with the piston manometer using gas as the working medium and the piston manometer using liquid as the working medium, due to the different working medium they use, the gas piston manometer has a long rotation duration, high sensitivity and good repeatability. The data is accurate and reliable.
