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.

Description
Key Features
- 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
- 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
