MTM Hydro's Pressure Gauges are meant to be paired with the top-mount or back-mount Pressure Gauge fitting (24.0101 or 22.0239) and are offered in several sizes of gauge between 3,600 PSI and 10,000 PSI in both, back and bottom styles. Once installed, this device effectively measures running pressure and catches spikes that occur when your gun trigger is released or engaged.
Use your assembled gauge to measure baseline PSI and compare against baseline at later dates for accuracy.
A primary fixed location is most commonly found immediately after the pump or on an unloader port to measure 'Pressure at the Pump' and catch pressure spikes. This location will also alert you of cavitation in pump that you may not hear or feel. The needle on the gauge will bounce and appear to be trembling
A second, temporary position is at the base of the spray gun for intermittent checking of pressure to ensure your nozzle does not need to be replaced. This will also catch pressure spikes and alert you of pressure changes over time as your nozzle enlarges due to wear.
