Hioki FT6380-50 Clamp-On Earth Tester

Hioki FT6380-50 Clamp-On Earth Tester

The Hioki FT6380-50 is a clamp-on earth resistance tester for multi-grounded systems, measuring from 0.20Ω to 1600Ω. Because it works by the clamp-on method, it measures earth resistance without driving auxiliary stakes or disconnecting the earth electrode — ideal for transmission towers, storage tanks and multi-point earth grids.

Key Features

• Clamp-on earth resistance measurement, 0.20Ω to 1600Ω
• True RMS current measurement (20mA to 60A)
• No auxiliary stakes required and no need to disconnect electrodes
• Φ32mm jaw for clamping earth conductors
• CAT IV 600V safety rating
• Bluetooth data transfer with the optional Z3210 adapter
• IP40 (jaws closed); LR6 alkaline battery ×2, approx. 35 hours operation

Included Accessories

Carrying case, resistance check loop (1Ω, 25Ω), strap, LR6 alkaline battery ×2, instruction manual.

Applications

Earth-resistance measurement on multi-grounded systems such as transmission towers, hazardous storage tanks and substation earth grids, where conventional fall-of-potential methods are impractical.
