The TSI HM675 Hydronic Manometer is used to balance hydronic heating and cooling systems, check pump performance and set balancing valves. The TSI HM675 can measure and display differential, high side, and low side pressures simultaneously, without the need to change hose connections or instrument valve settings. This Hydronic Manometer is equipped with inputs for two temperature probes and large backlit display for use in low light areas.

The TSI HM675 is designed with a differential pressure range of ±300 psi (±2068 kPa) and gauge pressure range -20 to 300 psi (-138 to 2068 kPa). Users can read in. H2O, ft. H2O, psi, in. Hg, mm H2O, kPa, mm Hg, or bar with the HM675. Housed in a robust, splash-proof case, the manometer is rugged yet lightweight at only 2.65 lbs (1.20 kg) with batteries.
