Earthing or grounding of electrical equipment is essential to maintain safety, protecting lives, as well as prevent damage to equipment. The FT6031-50 is a IP67 dustproof and waterproof two-pole or three-pole ground resistance tester with large, easy-to-read display, highly sensitive earthing rods, and innovative cable winder that significantly reduces the amount of time needed to complete earth resistance tests.
CAT IV 100 V, CAT III 150 V, CAT II 300 V

Wireless communication capability for even greater convenience than FT6031 (legacy model)
Compatible with Wireless Adapter Z3210 (optional). It transfers measurements to your smartphone or tablet and allows you to quickly create reports with field photos and drawings.
Easy! Just connect the optional Z3210 Wireless Adapter to your Hioki compatible instrument, to make it Bluetooth® ready.
Wirelessly connect Hioki-compliant instruments with a simple connection. Transmit measured values to your tablet or smartphone.
Excellent noise resistancev
Allowable earth potential: 25.0 V rms
Expanded allowable earth voltage range from 10 V rms to 25 V rms. Even in an environment where the earth voltage is 25 V rms, stable ground resistance can be measured.
Dustproof and waterproof enclosure for robust performance in the field
IP67 dustproof and waterproof
Since the FT6031-50’s enclosure is designed to keep out dust, it can be used with peace of mind in settings where it would be exposed to mud and dust. And if the instrument gets dirty, it can be rinsed clean with water.
Using a grounding resistance meter: Two-pole and three-pole methods
You can select from two grounding resistance measurement methods (two-pole or three-pole). The instrument switches the internal connection automatically when the selection key is pressed, so there is no need to connect a short bar or other fixture.
Dramatically faster measurement setup thanks to superior ease of use and digital operation
The FT6031-50’s supplemental grounding rods are thin, making it easier to insert them into, and remove them, from the ground. The rods are made of rigid, corrosion-resistance stainless steel.
In addition, the allowable resistance of the supplemental grounding electrodes has been increased by a factor of 10. This enhancement eliminates the inconvenience of setting and resetting the rods over and over again when the allowable resistance is exceeded, for example in dry soil conditions.
Digital grounding resistance meter featuring easy operation
The FT6031-50 is extremely easy to operate: just press the MEASURE key.
Cord winders keep measurement cords from getting twisted or tangled
When measuring grounding resistance, it takes time to put away the long measurement cords.
