Megger DET2/3 100M KIT [1008-989] High Performance Digital Ground Tester with 330 ft (100 m) Test Lead Kit. The Megger DET23100MKIT High Performance Digital Ground Tester with 330 ft (100 m) Test Kit is a robust and compact automatic earth (ground) test instrument designed to measure earth electrode resistance and soil resistivity. Designed 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), BS-EN-50122-1 (Railway Applications), and IEEE Standard 81.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.
