  • Allows up to 100 Cv (Kv) factors to be entered
  • Calculates brake power, heat flow, Cv (Kv) factors, and impeller sizing
  • Stores up to 4,000 data points for recall or downloading via USB interface
  • Robust, splash-proof case 
  • Meter weight with batteries is 2.65 lbs (1.20 kg)

Hydronic Manometer HM685 is used to balance hydronic heating and cooling systems, check pump performance and set balancing valves. 

It can measure and display differential, high side and low side pressures simultaneously, without the need to change hose connections or instrument valve settings. The easy setup and intuitive operation make this instrument very simple to use.

The TSI HM685 Is Supplied With:

  • Instrument
  • Hard carrying case
  • (2) 6.7 ft x ¼-in. (2 m x 6 mm) hoses with shut-off valves
  • (2) B&G readout probes
  • (2) P/T gauge adapter probes
  • Power cord
  • Temperature probe
  • CompuDat™ USB downloading software
  • USB interface cable
