Pressure Gauge for Reverse Osmosis Systems with 1/4" connection by Finerfilters
The PSM-1 is a high quality 0-150 psi Pressure gauge suitable for use with Reverse Osmosis (RO) units.
This gauge comes complete with 1/4" push fit fittings, allowing for easy installation into your existing Reverse Osmosis setup, provided it uses 1/4" tubing.
This pressure gauge is essential for monitoring the performance of your RO system. All RO membranes are reliant on a satisfactory supply pressure (minimum 3 bar of pressure but preferably 4 bar). Low water pressure is a leading cause of problems with reverse osmosis units, as low pressure can cause the unit to not work at its optimum potential. Low pressure can lead to low rejection rates, low flow rates and higher TDS readings. The use of a pressure gauge, when using a booster pump, is also recommended in order to ensure the pressure is within the optimum range.
This pressure gauge will allow you to monitor your membrane inlet pressure and provide a rough guide to when your pre-filters require replacing.
Please note – the pressure gauge is best effective installed away from any water pumps i.e on an RO unit after the pre-filters. Otherwise the pulse from the pump will cause the gauge to continually jump and not give an accurate reading.
