Megger DET2/2

The Megger DET2/2 Digital Earth/Ground Resistance Tester is a compact, robust instrument designed for measuring earth electrode resistance and soil resistivity. This tester employs the four-terminal measurement method, eliminating current circuit resistance interference and minimizing potential circuit resistance effects. Microprocessor-controlled, DET2/2 features a user-friendly design with a large, easy-to-read alphanumeric display. The resistance tester's simple keypad allows for adjusting test frequency, current level, and filtering to counter adverse testing conditions. Additionally, it provides excellent error detection capabilities and comprehensive test information.
