IP67 Dust & Waterproof rugged EARTH TESTER
Hard Case Model
- 3-Pole and 2-Pole Earth Resistance measurement (0.01 to 2000Ω)
- Waterproof design (IP67)
- Rotary Switch makes the user interface very intuitive
- Large LCD Display with Backlight
- LED to monitor correct / non correct auxiliary earth spike resistance
- Earth Voltage Measurement (AC/DC 0 to 300V)

Measurement of the earth electrode resistance (3-Pole method)
The international standard IEC 60364-6 provides information regarding the measurement of the resistance of an earth electrode for TT, TN and IT systems.
This measurement shall be made by the Volt-Amperometric method using two auxiliary earth electrodes.
The instrument that covers this requirement is the Earth Tester.
