Test lead 100 m for earth resistance measurements (on a reel) red

100 m Sonel test lead in red color with banana plugs ends. The test lead is dedicated to earth resistance measurements. 

The test lead on a drum reel is designed for measurements performed over large areas with significant distances between connecting point of the tested object and probes driven into ground. The reel is equipped with a terminal of banana type (4 mm) to provide two functions. The first one is connecting multiple drum cables into series. The second function involves connecting the reel with the meter - an additional short cable is used for this purpose. The entire device is completed with a metal, stabilizing stand.
