I bought it for checking the hydraulic pressure of the cylindrical polishing machine but as the hydraulic pressure of the polishing machine got back to 0 momentarily, the needle of the pressure gauge bent in several hours.
I think that it is unsuitable in places where ON, OFF are strong.
Since the meter pointer does not return to 0, it is replaced at the same time as the compressor repair. Although the old gauge is 2.5 MPa, the maximum working pressure is 0.85, so this product was made. It operates at the same level as the digital display value of the operation panel.
