Review on 🌊 Stainless Steel Malida Water Pressure Gauge for Aquarium Meter & Reverse Osmosis System Pump, 0-1.6MPa / 0-220psi, 1/4" Size by Maria Duncan

Works great just remember to use a pressure valve to measure PSI before installing (in my case) a reverse osmosis water filtration system. I used two valves to get the desired PSI. First a valve, then two water keys. Open both, then use the wrench closest to you to adjust until the desired pressure is reached. After that, you can use the key furthest from you to easily open and close without worrying about adjusting the water pressure every time. Let me know guys, I can go into great detail if you want.
