The HM675 and HM685 hydronic manometers are designed to balance hydronic heating and cooling systems, check pump performance and to set balancing valves. They can measure and display differential, high side, and low side pressure simultaneously, without having to change hose connections or instrument valve settings. Additionally, they both feature a backlit display and use four alkaline or NiMH rechargeable batteries to operate.
