Oxygen gauge and pressure gauge dual-purpose calibrator is suitable for measurement and inspection institutions at all levels and industrial and mining enterprises. It adopts the comparison method to verify ordinary pressure gauges and other oil-prohibited pressure gauges. The plug pump generates pressure, and a secondary oil-water isolation device is set up to transmit the pressure through the oil circuit and the water circuit. It can not only verify the pressure gauge, but also the oxygen meter, and it can be used for two purposes. The machine has a reasonable structure, easy operation, stable performance and safety. Durability, etc.
