With Oil Anti Vibration Water Filter Pressure Gauge Test Gauge To Measure Water Pipes RANG:0-1.6MPA ToolOOTDTYOnscribement:Pressure Range: 0-1.6MPA/0-220psThe pressure gauge is oil-filled and shockproofDimensions: 88x68x28mmInterface:1. Tap water interface (G1/2")2. Interface Water Purifiers (9mm)Usage:4 part is connected to tap water on tooth angle valve, open angle valve, water pressure can be measured. Close the angle valve, open the 2 pressure relief of the flush mounted valve, you can take it off. Tap Water Test Analysis: In general, I believe that 0.1Mpa = 10 meters, the pressure state of the water supply should not exceed 0.35MPa, which is thirty-five meters. If you live in a small high, tap water supply twice, then the end of the water pressure will be greatly increased, generally the maximum six kg in water pressure is 0.6mpa. Single pressure gauge (common) for use in pressure test water filter. (as shown in the figure below)Pure water machine test analysis:1, Can install very low water pressure, the water is too low, the water is small or not, can be equipped with a fully automatic self-priming booster pump.2, The installation of the pure water machine meet the pressure less than 0.05MPa, the pure water machine does not work after the water power. At this time, two wire low circuit voltage switch (or directly to remove the pressure switch), water supply, RO machine can start normally.3 when the raw water pressure installation gt; 0.35MPa, a reducing valve should be installed. Package Included:1 Set 2in 1 Tap Water Filter Pressure Gauge
