Vacuum gauge

Mainly used for testing vacuum pressure gauge or vacuum pressure transmitter, it is the most cost-effective vacuum calibration equipment. -0.1 ~ 0.25MPa, -0.1 ~ 0.4MPa, -0.1 ~ 0.6MPa range of 0.1 level, 0.16 level, 0.25 level and 0.4 level of precision pressure gauges, volume transmission manometer calibration manometer, pressure transmitters and so on. Indicators are in full compliance with JG236-2009 piston pressure vacuum gauge. National Measurement and Certification Regulations. The weights have been corrected for pressure deformation coefficient and local gravitational acceleration. Intentionally designed pressure conversion valve, when closed, can work alone without weights, that is, the piston manometer table can be used independently as a pressure pump or pressure source. The internal bellows pressure regulating system is used for excellent air tightness. Simultaneous verification of two inspected tables, the use of fast pressure joints, no leakage phenomenon.
