The safety of the Ningdian®
oxygen pressure gauge mainly depends on the entire production process of the manufacturer and whether it is operated in strict accordance with the relevant national regulations. Many manufacturers use the standard pressure gauge as an
oxygen pressure gauge after cleaning with carbon tetrachloride, which can easily cause safety accidents. Therefore, it is recommended that you choose a good manufacturer when purchasing an
oxygen pressure gauge from China.
The main difference between the
oxygen pressure gauge and the dry pressure gauge is that the Ningdian®
oxygen pressure gauge is an oil-free gauge, that is to say, the final calibration of the assembled pressure gauge is to verify the pressure of the instrument by gas or water, while the standard pressure gauge is to be calibrated by oil. Calibration, because oxygen cannot spontaneously ignite but it can support combustion. Oxygen will have a violent chemical reaction with grease when the pressure is above 2.49MPa, so it must be prohibited.
