TSI HYDRONIC MANOMETERS MODELS HM675 & HM685

The HM675 and HM685 Hydronic Manometers are designed to efficiently balance hydronic heating and cooling systems, verify pump performance, and set balancing valves. These instruments allow for simultaneous measurement and display of differential, high-side, and low-side pressure without the need to change hose connections or adjust instrument valves. They feature a backlit display for ease of use in low-light conditions and operate on four alkaline or NiMH rechargeable batteries.
