The ELB series high-precision pressure gauge calibration bench utilizes a liquid medium (such as water or oil) and is designed for the calibration and testing of instruments including high-precision dial pressure gauges (Bourdon tube type), pressure sensors, pressure transmitters, pressure switches, and digital manometers. It offers a control accuracy of ±0.2% of full scale; specifically, the error remains within 0.2% of the gauge’s upper range limit during both the ascending and descending pressure phases of calibration, while consistent repeatability is maintained throughout the entire process.
