Analogue Earth Tester
Classic Ground Resistance Tester Using 3-Pole Method with Easy Cord Winding System
Earthing or grounding of electrical equipment is essential to maintain safety, protecting lives, as well as to 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.
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
