The Hioki FT6041 Earth Tester is a professional ground resistance testing instrument built for fast, accurate, and reliable field measurements. Designed for electricians, maintenance teams, utility technicians, contractors, and grounding system inspectors, it helps measure ground resistance, soil resistivity, ground potential, and low resistance in demanding jobsite conditions.
The FT6041 supports a wide range of measurement methods, including 4 pole, 3 pole, 2 pole, MEC, 2 clamp, and low resistance testing. Its MEC Measuring Earth with a Clamp function helps measure ground resistance without disconnecting the grounding electrode, reducing work time and improving efficiency during inspections. The tester is also suitable for soil resistivity surveys when designing grounding systems.
Built for tough outdoor use, the Hioki FT6041 features IP65 and IP67 dustproof and waterproof protection, a wide operating temperature range from minus 25°C to 65°C, and a drop proof design with protector attached. It also delivers fast 3 pole measurements in approximately 6 seconds, while the cord rewinding system helps reduce tangles and makes field work easier.
For modern reporting and data management, the FT6041 can transfer measurement data to a smartphone or tablet when used with the optional Hioki Z3210 Wireless Adapter. With the GENNECT Cross app, users can manage readings, add field photos, include handwritten notes, and create professional reports more efficiently.
