How to read a Shock-proof pressure gauge?

　　You can read the pressure gauge by simply matching the pointer to the number on the dial. The digital shock-proof pressure gauge will read the accurate PSI, while a pressure gauge like a tire pressure gauge will shoot a small stick marked PSI. The stick will be aligned with the end of the pressure gauge so you can read the pressure.

　　If the shock-proof pressure gauge reads negative, what does it mean?

　　Obviously, the negative pressure gauge reading is problematic. Normally, the pressure gauge ranges from zero to any positive number. Therefore, if your shock-proof pressure gauge shows a negative number, either the Shock-proof pressure gauge is malfunctioning, or its working principle is a vacuum. Pull the Bourdon tube to a farther curve, which will make the pointer go down. This may be because the pressure gauge is not properly calibrated or needs to be calibrated.

　　A shock-proof pressure gauge is a great tool for measuring the pressure of your water treatment system. They allow us to really see how our equipment works and how our filters work. Very specifically, they are monitoring devices. The pressure gauge will not cause a problem, but it will definitely tell you if there is a problem with any of your water filtration equipment or systems.
