Digital Clamp-on Earth Resistance Tester
Motwane’s Digital Clamp-On Earth Resistance Testers – the DECT-2 and DECT-3 – are cutting-edge tools crafted to measure earth resistance quickly, safely, and accurately, all thanks to their modern clamp-on technology.
This innovative approach means you don’t have to disconnect the ground rod, making it perfect for locations where multiple grounds are set up in parallel. Just clamp it around the conductor or earthing strip, and you’ll get precise resistance readings, allowing for efficient testing without any disruption to the grounding system.
