Is the ordinary pressure gauge oil resistant and vacuum resistant?
The use of pressure gauges should be chosen according to the specific working conditions.
Normal pressure meter is one kind of pressure gauge, there are vacuum pressure gauge, gas can measurement no corrosion to copper alloy, liquid (including oil), oil resistance, what you said is not oil proof, ordinary pressure gauge is not proof
For ordinary pressure gauge, its material for oil tolerance is no problem, and its influence on oil resistance is the main component of the gasket.For pressure gauges with a pressure greater than 0.1MPA, there is also the ability to resist vacuum.But generally speaking, the role of instrument is for practical use, and the instrument must comply with the selection criteria, if it is used to measure the parameters, only do it immersion test or vacuum test, this idea seems to have no practical value.
