ANALOG EARTH TESTER FT3151

Earthing or grounding of electrical equipment is essential to maintain safety, protecting lives, as well as prevent damage to equipment. The FT3151 Analog EarthTester uses the AC phase differential system to measure earthing resistance, which assures that accurate measurements are unaffected by earth voltage and auxiliary earthing resistance. New innovate cord winders make clean up a breeze.

CAT II 300 V

Key Features

Three-electrode method, Two-electrode method (Simple Measurement)
Wide measurement range for 0 to 1150 Ω, based on EN standard
Switchable measurement frequency to reduce the effects of power supply harmonics
Dramatically faster setup: Comes with improved earthing rods and cord winders

Model No. (Order Code)
