FT6041‑91 Earth Tester – 4‑Pole & MEC Function

Hioki FT6041-91 Earth Tester with Clamp Sensors – 4-Pole & MEC Function

The Hioki FT6041-91 Earth Tester Kit is a versatile, professional-grade solution for accurate ground resistance testing in electrical, industrial, and power applications. Combining the FT6041 earth resistance meter with the FT9847 and CT9848 clamp sensors, this kit supports multiple testing methods, making it one of the most flexible earth testers available.

Engineered for power distribution systems, grounding installations, and maintenance professionals, the FT6041-91 allows measurements without disconnecting electrodes. It supports 4-pole, 3-pole, MEC (measuring earth with a clamp), and 2-clamp techniques, enabling fast, safe, and reliable ground resistance evaluation — even across multiple grounding points.

Designed with an IP67-rated housing for dust and water protection, the FT6041-91 is built for rugged environments. With tangle-free cord rewinding, easy-to-use clamp sensors for narrow and wide bus bars, and smart connectivity via GENNECT Cross app (with optional Z3210), this earth tester streamlines field testing and reporting.
