Megger DET2-3 Advanced Earth Ground Tester 1008-942
High resolution of 1 mΩ, ideal for large earth (ground) systems
The Megger® DET2/3 automatic earth (ground) test instrument is robust, compact and designed to measure earth Electrode Resistance and Soil Resistivity. 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 is a reliable instrument for use 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 / grounding), BS-EN-62305 (Lightning Protection), IEEE Standard 81 and Railway Applications. Soil Resistivity measurements are used to establish the optimum electrode design and site, as well as archaeological and geological investigations.
*Important Calibration Information:
This instrument comes complete with the manufacturers calibration certificate. Please be aware that these certificates are generic and may also be time lapsed.
If you would prefer a personalised full traceable calibration certificate applied to the equipment before dispatch, then please select this option from the drop-down menu above, an additional calibration charge will apply.

High accuracy earth (ground) measurements
The DET2/3 provides accurate 1 mΩ resolution measurements of earth (ground) electrode resistance. With its microprocessor controlled system it provides a flexible and ‘user-friendly’ approach to earth tests by the provision of excellent error detection capabilities and full test information shown on a large colour display. Test frequency, test voltage and filtering can be quickly and easily adjusted so that adverse conditions, which can influence the test, can be overcome.
A wide band of test frequencies, with a resolution of 0.5 Hz, can be used to eliminate errors caused by noise in the earth. The DET2/3 also includes an automatic frequency selection feature that scans for frequencies with the lowest noise level and then runs a test at that frequency.
Continuity measurements and bonding
- Single resistance range: One fully automatic range from 0.01 Ω to 1.0 kΩ
- Display: Three digit display n Accuracy: ±3% (±2 digits)
- Short circuit current: 200 mA continuity test currents
- Lead null: Lead resistance compensation (NULL) operates with a lead resistance up to 10 Ω
Trace display and data storage
Utilising the latest processors, the DET2/3 can provide a live trace of its measurements, which graphically shows the amount of noise from the system under test - a powerful diagnostic tool for the expert earth (ground) test engineer. Use of the latest processors and a large internal memory allows for immediate calculations of resistivity (Wenner or Schlumberger method) and the ability to save a complete day’s worth of test results. Test result data can be downloaded directly through a USB flash drive or straight to a Windows PC running PowerDB™ software.
