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.

Vibration-Resistant Drinking Water Pressure Gauges

Bottom Connection

Clearly read pressure levels in your drinking water system, even with heavy vibration. The dial face is filled with glycerin, which absorbs shock and keeps the needle steady. These gauges meet NSF/ANSI 61 for drinking water. Mount them with the dial face upright.
