0-400 PSI Pressure Gauge for Water Treatment System

316 Stainless Steel | Panel Mount Back Connection | Liquid Filled 2.5" Dial

AMI Liquid filled pressure gauges are used to monitor the pressure in a water line and are most commonly used to measure the RO system pressure (concentrate pressure) in a tap or brackish water RO system. AMI panel-mount (back-connection) gauges are intended for mounting to the control panel of a commercial RO system or other water treatment system.  The dial is 2-1/2" and liquid filled for extended service life and shock resistance.   The wetted parts are constructed of 316 stainless steel.
