HM685
The TSI HM685 Hydronic Manometer aids in balancing systems, checking pump performance, and setting balancing valves. It measures and displays differential, high-side, and low-side pressures simultaneously. It includes various measurement units like psi, kPa, H2O, etc.
The manometer measures differential pressures up to ±300 psi and gauge pressures from -20 to 300 psi. It also supports two temperature probes for advanced calculations, for example, universal flow and BTU/hr assessments. The HM685 can store up to 4,000 data points and has heat flow, brake power, and impeller sizing calculation characteristics.
