The Megger DET2/3 automatic earth test instrument is designed to measure earth Electrode Resistance and Soil Resistivity, with highly accurate results. It provides a full range of test methods and excels at the four terminal method of measurement, which eliminates the resistance of the current circuit from the measurement.

The DET2/3 can be used on large or more complex earth systems, which include communications earth systems and difficult test environments. It can be used to test in accordance with BS 7430 (Earthing), BS-EN-62305 (Lightning Protection), BS-EN-50122-1 (Railway Applications) and IEEE Standard 81.

The DET2/3 can be used in agricultural locations (as per IEC 61557-5) where, to comply with the standard, the output voltage must be set to 15 V. It can also set to 15 V when risk assessment determines that a 50 V test voltage is too high.

The DET2/3 is sealed to IP54 standard, which provides weatherproofing during operation (case lid open). When the case lid is closed its protection standard is to IP65 (water and dust damage). The DET2/3 is powered by an internal rechargeable battery which has a long usage period. The battery is recharged with an external power supply unit.
