Features

Amprobe Automatic AC71B Clamp Multimeter is the automatic everything clamp meter. AutoTect feature automatically senses what type of measurement is being made when the test leads are placed across a measurement point. There is no knob to turn. The meter knows what is being measured and the digital display shows the measured value along with the associated unit icon. AutoTect also utilizes a lower input impedance. This helps determine if voltage is from leakage (called ghost voltages) or a hard connection. Any ghost voltages will be zeroed out by the lower input impedance.

Amprobe AC75B Digital Clamp Meter with Temperature is three tools in one: clamp meter,multimeter and thermometer. The extra features of the AC75B enable more specialized troubleshooting. Custom designed to make HVAC/R service, electrical and industrial maintenance tasks faster and easier. Amprobe AC75B combines a heavy duty high-capacity 600 A clamp-on meter with the most needed DMM functions such as resistance, continuity and voltage measurement for general electrical troubleshooting.
