Test lead 30 m for earth resistance measurements (on a reel, banana plugs) red
30 m Sonel test lead in red color with banana plugs ends. The test lead is dedicated to earth resistance measurements.
Test leads on reels are designed specifically for outdoor work - they have increased resistance to mechanical damage. One end of the test leads is terminated with a secure banana plug (4 mm), while the other end has a 4 mm lamella for connecting it to the reel and directly to the probe driven into the ground.
