TSI HM675 & HM685 Hydronic Manometers

The HM675 and HM685 Hydronic Manometers by TSI Instruments are used to balance hydronic heating and, check pump performance to set balancing valves and cooling systems.

Displaying differential, high side and low side pressure and can measure simultaneously, instrument valve settings or having to change hose connections.

Each model displays a backlit screen and operates on NiMH rechargeable batteries or four alkaline batteries.

Features and Benefits:

  Measure and display differential pressure simultaneously high side and low side from 0 to 300 psi (0 to 2,068 kPa)
  Robust, splash-proof case
  Inputs for two temperature probes

Features and Benefits (HM685):

  Using valve manufacturers’ Cv (Kv) factors [up to 100 Cv (Kv) can be entered] calculates flow
  Calculates heat flow, impeller diameter and brake power
  Stores up to 4,000 data points to memory for later recall/download to a PC using CompuDat™ USB Software and USB interface cable
  For easy navigation and instrument set up an intuitive menu structure


  Balance and test cooling and heating systems
  Check pump performance
  Set balancing valves
