Watts 0036520|WW0036520 - GAGE-PG8 0-135IN

This differential pressure meter kit is designed to measure differential pressures on flow measurement valves and flow measurement orifices in 0-135 IN of water. It provides over range protection at an accuracy of plus or minus 3 percent. It consists of a differential meter, two color-coded hoses with brass coupler, two air venting valves with hoses, meter balance valve, brass filter with plastic housing, carrying case, and instruction manual. It will also check differential pressures across other system components such as, pumps, strainers, and coils.
