Product Details

Catu Earth & Ground Resistance Tester

The Catu earth and ground resistance tester measure a 1.999kΩ absolute maximum resistance and is having a CAT III safety category. This tester is used to ensure proper operation of the earthing system. It emits a sound signal for continuity checks and directly displays the value on the LED screen. It is also used to measure the electrical characteristics of a system. The measurement of the earth resistance, performed by this device, is based on the measurement principle called "fault loop". The measurement is carried out with an accuracy of (+/-3% +1 digit) on pure resistance, range of 0-200 Ω at 23 °C +/-5°C.

Features and Benefits

• Available with a touch point on extension cord of 7m and instructions for use, without a case
• Displays the presence of Voltage and the phase position
• Measures the earth loop (fault loop) without tripping the circuit breakers: <15 mA
• Non-slip coating for a better grip
• Once connected to a properly connected installation, the earth value is displayed instantly on the top of the 4-digit LCD display that can indicate earth resistance values ranging between 0 and 100Ω in blue colour digits (at the 100 Ω threshold recommended by NF C 15-100) and between 101Ω and 1999Ω in red colour digits
• Operating temperature ranges between -150C and 450C
• Total autonomy (without battery)
• Two-way use: 2P + T socket or LV switchboard with cord


• EN 61557-4
• IEC 61010-1
• IK06 rated
• IP40 rated
• NF C15-100
