Vacuum gauge calibration

A vacuum pump is definitely necessary, but a controller is also essential
Just buy a pressure calibrator.
Why go to the trouble of dealing with a pressure gauge? If you doubt its accuracy, just blow on it – that will ruin the diaphragm inside the gauge, and in that case it’s better to replace it with a new one. It is recommended that instead of a vacuum gauge, a micro-pressure gauge be used for this type of pressure meter, with a range of -100 to 100 Pa
For vacuum pumps, we build the frame by ourselves; that’s how we do it……
I didn’t say gauge pressure of -100 Pa
A negative pressure of 100 Pa is indicated by a regular pressure gauge; equipment calibration is available everywhere
Hehe. . . What do you mean by 100Pa? ? ? If the absolute pressure is 100 Pa, it is no longer called a vacuum gauge. .
