TSI Alnor HM670 and HM680 Hydronic Manometers for System Balancing

Facilities with hydronic (water) systems are typically balanced for terminal flow using differential pressures. Balancing hydronic systems reduces energy consumption and saves money. TSI Alnor HM670 and HM680 manometers are used to balance hydronic heating and cooling systems and to check pump performance. Both models can measure and display differential pressure, high side gauge pressure, and low side gauge pressures simultaneously without the need to change hose connections or instrument valve settings.

The HM680 manometer includes a meter, a 6" temperature probe, hard carrying case, two hoses with shut-off valves, two P/T gauge adapter probes, B&G readout probes, two flare to NPT fittings, AC adapter, NiMH batteries, external battery charger, neck strap, user manual, and NIST traceability certificate.

Key Specifications

• Measuring range: 0 PSI to 300 PSI (0 kPa to 2068 kPa)
• Measures and displays high side, low side, and differential pressure simultaneously
• Large backlit display for use in low light areas
• Operates on four Alkaline or NiMH rechargeable batteries
• Robust splash-proof case
• HM680 calculates flow using valve manufacturers' Cv flow factors, and calculates heat flow, impeller diameter, and brake power
