Product Details:

The Amprobe DGC-1000A is an easy to use earth resistance clamp meter that delivers accurate ground resistance readings from 0.025 to 1500Ω (regardless of power quality) in less than ten seconds. If the measured resistance is lower than 40.00Ω, a continuous beep will sound to alert the user.

A must-have tool for any electrical contractor, the DGC-1000A earth resistance clamp meter has an onboard memory and data logging facility (of up to 116 records) for increased efficiency, with individual data point recording. The high and low ohm audible alarms are also selectable by the user for further personalisation.

The auto power-off function preserves battery life and can be disabled if required.

No test leads or auxiliary electrodes are necessary with the Amprobe DGC-1000A model and safety is amongst its top features, meeting full compliance with EN 61010, CAT III/300V, and CAT II/600V.
