With oil Anti-vibration water purifier pressure gauge Test meter to measure water pipes RANG:0-1.6MPA tool Description: Pressure range:0-1.6MPA / 0-220psi Pressure gauge is Oil-filled and shock-proof Dimensions: 88x68x28mm Interface: 1.Tap water interface(G1/2") 2.Water purifiers interface(9mm) How to use: The 4 part is connected to the tap water at the tooth angle for valve, open angle for valve, water pressure can be measured. Close the angle for valve, open the 2 sub - flush for valve pressure relief, you can take off. Tap water test analysis: Generally believe that 0.1Mpa = 10 meters, the state of the water supply pressure should not exceed 0.35MPa, that is, thirty-five meters. If you are living in a small high, tap water supply by two times, then the end of the water pressure will be greatly increased, generally the maximum of six kg in the water pressure is 0.6Mpa. Single pressure gauge (joint one) for use in water purifier piping pressure test.(as shown in the figure below) Test analysis of pure water machine: 1, the opportunity to install the ultra low water pressure, the water is too low, the water is small or not, can be equipped with full automatic self suction booster pump. 2, the installation of pure water machine encounter pressure less than 0.05MPa, pure water machine does not work after the water power. At this for time the two wire low voltage switch short circuit (or directly to remove pressure switch), water supply, RO machine can start normally. 3, when the installation of for raw water pressure >0.35MPa, please be sure to install pressure reducing for valve. Package include: 1 set of 2in1 Water Purifier Tap Pipes Pressure Gauge
