HVAC Clamp Meter

HVAC service technicians, contractors, and maintenance personnel need good diagnostic tools for working on electrical wiring or motors. An HVAC clamp meter is a great tool for troubleshooting many issues.

Clamp meters read AC amps with the use of a clamp so techs don’t have to disconnect any wires. These instruments measure AC amps, AC and DC voltage, test capacitors, and read ohms to check insulation resistance. A good HVAC clamp meter should also be auto-ranging and have surge protection.

What is the difference between common clamp meters and HVAC meters?

HVAC clamp meter ranges should be both lower and higher than those in a multifunction meter, depending on the test. The instrument should read current from 1/100 to at least 300 amps, volts up to 600 VAC and 300 VDC with a resolution of 1 millivolt, resistance from 1/10 to 5 MOhms, and be able to measure micro amps.

Valuetesters.com has a wide range of such instruments from well-known brands like Amprobe, Extech, Fieldpiece, Flir, Fluke, Klein Tools, Testo and UEi. We would also like to direct your attention to the newest instrument from Testo, model 770-3.
