The TSI HM685 Hydronic Manometer and data logger 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. Includes downloading software, computer cable and temperature probe.
