Drinking Water Pressure Gauges

Top Connection

Check the pressure on your drinking water system with these gauges—they meet NSF/ANSI Standard 61 for safe use with potable water. The dry dial on these gauges is best for low-vibration applications, since the needle can bounce if the gauge is shaken. For more accurate readings under heavy vibration, use a liquid-filled gauge. Mount gauges with the dial face upright.
