What is an oxygen pressure gauge?

What is an oxygen pressure gauge, and what material is it made of? Can stainless steel be used alongside copper? It seems that only a ban on oil is required, with no other requirements, is that right?
An oxygen pressure gauge is a type of gauge used to measure oxygen pressure. It measures gauge pressure, and due to the strong oxidizing nature of oxygen, a special gauge is required for measuring its pressure – and this is the oxygen pressure gauge. There are clear regulations and specifications for oxygen pressure gauges; in simple terms, there are two key points: no oils or greases of any kind may come into contact with them, from the stage of manufacturing components to the process of assembly and calibration, and the dial features a red mark indicating that oils are prohibited. brass
Oxygen cleaning is sufficient; oil-free conditions are required. Both brass and stainless steel work, but brass is less expensive and also looks better
No requirements regarding the material; it just needs to be oil-resistant....
What the people above said is all correct. Oxygen pressure gauges require degreasing and deesterification, and oil must be avoided during use. Additionally, if gaskets are required, they should generally be made of fluororubber or fluoroplastic materials; polyolefin materials cannot be used.
Oxygen meters require degreasing (oil-free). Copper is a good compatible material with oxygen, but stainless steel is still more commonly used. . .
