FLOW Pressure and Temperature Gauge - High Accuracy Digital Monitor for Hydraulic Systems, HVAC, Industrial Equipment | Perfect for Water Pumps, Compressors, and Machinery Maintenance

Reach-iT FLOW and TEMPERATURE GAUGE. 

By switching the lever on the back of FLOW RED  to 'OFF', you can measure the water pressure at spigot.

By switching the lever on the back of FLOW RED to 'ON', you can measure the operating pressure.

Temperature seriously affects the performance of all RO MEMBRANES - with inlet water temperature  at 75 degrees F (Factory rating conditions)(25C), an RO performs DOUBLE the pure water production compared to when inlet water temperature is 39 degrees F (6C). 

This is particularly important when starting Window Cleaning again in Spring - the ground temperature might be close to 30 degrees (and our water supply comes from underground), even if the nice Spring day is 60 degrees, so you will understand why the flowrate is not as good as you remember at the end of the fall season (applicable in cold areas).

If applicable, overcome this temperature induced flowrate issue with a BOOSTER PUMP.
