The TSI Alnor HM670 hydronic manometer is a precision multi-function instrument designed primarily to balance hydronic heating and cooling systems and to check pump performance. A versatile, handheld tool in a robust, splash-proof case, the HM670 accurately measures pressure, temperature and flow making it an indispensible item in the HVAC technicians tool kit.

TSI Alnor HM680 hydronic manometers measure and display differential, high side, and low side pressures from 0 to 300 psi simultaneously without having to change hose connections or instrument valve settings. The basic accuracy on pressure readings is ±1% of reading or .072 psi, whichever is greater. Temperature readings from -40 to 250°F can be made with the included temperature probe. An accuracy of ±0.5°F is possible for temperatures from 32 to 160°F (±2.0°F otherwise). Flow ranges for the HM680 are 0 to 9,999 gpm. Accuracy is dependent upon pressure accuracy plus valve deviation. Results for all measurements can be shown in a wide range of engineering units on the backlit display.

The TSI Alnor HM670 hydronic manometer ships complete with meter, (2) B&G readout probes, (2) P/T gauge adapter probes, (2) 6.7 ft x ¼-in. (2 m x 6 mm) hoses with shut-off valves, hard carrying case, and power cord.
