Megger DET2/3 Advanced Earth (Ground) Tester
Megger DET2/3 Advanced Earth (Ground) Tester
(Based On 10 Reviews)
The Megger® DET2/3 is a durable and compact instrument designed for accurate testing of earth electrode resistance and soil resistivity. It supports multiple test methods, with a focus on the four-terminal method, which ensures high accuracy by eliminating current circuit resistance. Ideal for large or complex earthing systems, it meets standards like BS 7430, BS EN 62305, and IEEE 81. It’s also suitable for lightning protection systems, railway applications, and even archaeological or geological investigations.
