Red FlagPrecision Pressure GaugeIt consists of a pressure measurement system, transmission mechanism, indicator device, and housing. The pressure measuring elastic element of the precision pressure gauge is treated with special technology to ensure stable and reliable performance of the precision pressure gauge. After being matched and debugged with a high-precision transmission mechanism, the indication accuracy can be guaranteed. Precision pressure gauges are mainly used to calibrate ordinary industrial pressure gauges, and can also measure the pressure of non corrosive, non crystalline, and non solidifying media such as copper alloys and alloy structural steels on the process site. The precision pressure gauge is equipped with a mirror ring (A-type B-type) below the scale line, which provides clearer readings during use.

The working principle of a precision pressure gauge is that when the pressure of the measured medium acts on the elastic element, it produces elastic deformation displacement, which is amplified by the transmission mechanism driven by the pull rod, and the measured pressure is indicated by the indicator device.
Precision pressure gauges are classified according to accuracy: 0.25%, 0.4%

The basic requirements for calibration are as follows:
If the environmental condition calibration is carried out in the calibration room, the environmental conditions should meet the laboratory's requirements for temperature, humidity, and other regulations. If calibration is carried out on site, the environmental conditions shall be based on the conditions that can meet the on-site use of the instrument.
As a standard instrument for calibration, the error limit of the instrument should be 1/3 to 1/10 of the error limit of the calibrated meter.
Although personnel calibration is different from verification, the personnel conducting calibration should also undergo effective assessment and obtain corresponding qualification certificates. Only certified personnel can issue calibration certificates and reports, and only such certificates and reports are considered valid.
Tire pressure gauge calibration can be found at local metrology institutes or third-party calibration units, such as Shanghai Metrology Institute, Guangdong Metrology Institute, Suzhou Metrology Calibration Network, etc All prerequisites must have CNAS metrology qualifications issued by the state.
