Description

The Extech 382357 is an Autoranging Non-Contact Clamp-On Ground Resistance Tester which will take measurements of ground conductors without the need for auxiliary ground spikes. The 382357 will take True-RMS AC leakage measurements from 0.2 mA up to 30.0A and can accomodate larger ground rods with the 0.9″ (23 mm) jaw size. The 382357 features a 9999 count LCD display with Data Hold and includes a programmable Hi/Low alarm as well as programmable datalogging for up to 116 data points.
