The 54846 RO Tank Pressure Gauge measures air pressure per square inch (PSI) in 1/2 PSI increments. Standard 3.2 gallon water holding tanks should be 8 PSI when empty, and 36 PSI when full. This gauge is the obvious choice for keeping your RO tank in the effective range. Over time, any RO holding tank will lose some pressure--so stay on top of it with this handy tool!
- Easily checks the air pressure for your reverse osmosis water tank
