Extech 382357 Clamp-On Ground Resistance Tester
Completely non-contact measurements of ground conductors are simple with the Extech 382357 – it doesn’t even require auxiliary spikes to operate!
This earth clamp meter can perform fully auto-ranging measurements of ground resistance from 0.03 to 1500Ω with a resolution of 0.002Ω for extra precision. A dedicated AC leakage current (true RMS) function is also included and can measure across a range of 0.2mA to 30.00A.
The Extech 382357 has a built-in data-logging capability with programmable logging points. It can store up to 116 data points and comes with programmable high/low alarms which will alert the user if spikes/drops are detected.
The jaws of this clamp meter are 0.9” (23mm) in diameter and are suitable for use with large ground rods.
