In order to allow users to better understand the double piston pressure gauge, we will detail the advantages and characteristics of the double piston pressure gauge from 11 aspects to help you better choose the double piston pressure gauge

1) The new double piston pressure vacuum gauge is based on the same type of other domestic, the use of international advanced technology, advanced technology, completely changed the original double piston pressure vacuum gauge due to congenital deficiency caused by unstable piston balance, inaccurate measurement phenomenon, to provide customers with a new quality double piston pressure vacuum gauge, It completely solves the problem that vacuum and low pressure measurement is not ideal, and provides an ideal standard instrument for pressure value transmission and precision pressure measurement in China.
2) Comply with the new regulations JJG159-2008 “Double piston pressure vacuum gauge” national metrological verification regulations and JJG99-2006 “Weights” national metrological verification regulations.
3) Good stability, easy adjustment, accurate reading, sensitivity less than 5 mg, can measure precision pressure gauges and pressure transmitters (pressure sensors) below 10kPa, the minimum weight can be customized for 1kPa, no blind spot between -0.1 and 1MPa.
4) It can be used as a verified piston pressure gauge for transmission; It can also be used for high-precision testing; Available with kg weights and Mpa weights.
5) The pressure deformation coefficient and local gravitational acceleration of the weights have been corrected.
6) Verification certificate can be issued; The double-piston pressure vacuum gauge with accuracy class 0.01 can only open a calibration certificate according to national regulations.
7) When testing, adding weights is more convenient and quick, and it is not necessary to turn the piston head like the old piston, and it can be loaded directly.
8) The oil compressor and oil and gas isolation equipment material is plexiglass, high strength, good transparency, can be more direct observation of the oil level.
9) The body itself is equipped with a fine-tuning valve, so that the pressure regulation is faster and the reaction time is shorter.
10) Equipped with a stop valve, if the air source is found to be unstable, you can turn off the stop valve, so that the air source is disconnected, and the piston pressure is more stable. When pressurizing, only one manual pressure pump can be used, and vacuum pumps and air compressors are no longer needed.
11) Beautiful appearance, stainless steel wire drawing surface, no longer worry about the tools and the instrument to be scratched the surface.
