Product Details

Catohm NG DT300 Loop Controller

A device designed to easily measure earth resistance (in TT), monitor continuities and check installations (on standard 2P + T plugs or B.T. panels).
On its dual-colour LCD screen, the Catohm NG clearly and instantly displays the correct plug connection, as well as the earth resistance value, whose colour changes from blue to red beyond the 100 Ω limit (max. limit value set by NF C 15-100).

Standards

NFC15-100, IEC 61010-1 and EN 61557-4

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

Certifications

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