• Design: Handheld (203 x 148 x 78 mm, 1 kg), IP54, CAT IV 100 V, AA batteries (700 tests). 

• User-Friendly: Large LCD, one-button operation, voltmeter, automatic checks, selectable test voltage (25/50 V). 

• Complete Kit: Tester, leads/stakes, batteries, calibration certificate, hard carry case; optional clamps, ETK kits.

The Megger DET4 Series (DET4TD2, DET4TR2, DET4TC2, DET4TCR2) 4-Terminal Earth/Ground Resistance and Soil Resistivity Testers offer 2/3/4-point, ART, and stakeless testing for ground resistance (0.01 Ω to 200 kΩ) and voltage (0-100 V), with selectable frequencies and noise rejection up to 40 V pk-pk.

Rated IP54 and CAT IV 100 V, the handheld units (1 kg) use AA batteries (700 tests) and are ideal for buildings, pylons, and RF sites. The TC2/TCR2 models add current measurement and ART/stakeless capabilities. Compliant with BS 7430, BS-EN-62305, IEEE 81, the kit includes leads, stakes, batteries, certificate, and case, with no warranty specified, suitable for utility and industrial grounding tests.
