Earth Testers

Earth 2/3 MI 2126

Earth 2/3 is a professional, hand–held, battery powered test instrument. It is intended for carrying out earth resistance measurements in accordance with European standard EN 61557 - 5.
It facilitates with the Earth resistance measurement for:

• 2-pole and 3-pole measurements.
• Reliable measurement results also at presence of stray currents.
• Outstanding repeatability of measurement results also in case of high test probe resistance at various earthing structures (e.g.: asphalt, sand, stone).
• Warnings for out of limits results and incorrect test conditions.
• Auto power-off..

It is the best Digital measuring instrument for measurement on earthing and lightning protection systems. It facilitates the following:

• Measurements on earthing and lightning protection systems include:

1. standard 4-wire method,
2. standard 4-wire method with current clamps
3. 2-clamp method without junctions disassembling.

• Specific earth resistance (soil resistance) measurement with 4-wire method up to 30 m deep.
• True RMS current measurement.

It is a Multifunction, digital measuring instrument for testing of earthing and lighting protection systems, PE conductor continuity testing and DC insulation resistance measurement on low voltage electrical installations in accordance with EN 61557. Measurements on earthing and lightning protection systems include: standard 4-wire method, standard 4-wire method with current clamps and 2-clamp method without junctions disassembling.

• Specific earth resistance (soil resistance).
• DC insulation resistance measurement with test voltages from 50 V up to 1000 V in 10 V steps.
• Measuring range up to 30 G Ohm.
• mains voltage and frequency measurement
• clamp current measurement
• varistor testing.
• Internal memory with a capability to store up to 1000 test results that can later be transferred to a personal computer.

MI 3123 : SMARTEC Earth / Clamp for testing earthing resistance, main earthing of objects, resistance of individual earthing rods in large systems, lightning systems, determination of soil resistivity, designing of earthing systems. It is suitable for testing on CAT IV installations.
