HIOKI FT6380-50 kit – Wireless Clamp On Earth Tester

Item Number: HUFT6380-50 KIT Categories: , , , Tag:


The Hioki FT6380-50 KIT Digital Clamp On Earth Tester/Ground Resistance Tester Kit includes the FT6380-50, which measures grounding resistance simply by clamping to multiple-grounded ground wires. No auxiliary grounding rod is needed, and there is no need to disconnect the ground wire from the grounding rod.

The compact, low-profile sensor can be used to clamp ground wires with ease, while also providing AC current measurement functionality; it can measure currents ranging from leakage current on the order of several mA to load currents of up to 60 A. The FT6380-50 KIT also includes the Z3210 wireless adapter that enables the use of Gennect Cross, a complimentary app that allows users to check and manage measurement results and create reports.
