Offering inputs for 2 temperature probes to maximize efficiency, Models HM675 and HM685 are used to balance commercial hydronic heating and cooling systems, check pump performance, and set balancing valves. Model HM685 performs onboard universal flow and btu/hr calculations and allows for 4X more storage capacity. Both splashproof models can simultaneously measure and display differential, high side, and low side pressure without changing hose connections or instrument valve settings.
