The Megger DET24C clamp-on earth tester is designed with flat core ends to prevent dirt build up, ensuring measurement integrity and improved reliability over previous products with interlocking teeth. Other enhancements include improved accuracy, ultra high battery life, safety to CAT IV 600V and a built in filter function for electrically noisy environments.

The Megger DET24C features elliptical jaws, and the clamp jaws also have flat faces, making them much easier to clean and much less prone to damage than clamps have interlocking laminated faces.


Elliptical clamp shape improves access to earth cables and straps up to 50 mm.
Low maintenance flat jaw interface.
Measures ground resistance from 0.05 Ω to 1500 Ω.
Measures true RMS ground leakage current from 0.5 mA rms to 35 A rms.
CAT IV 600 V safety rating.
Memory to record and view results.
Backlit LCD display.
Automatic self calibration.
Auto ranging.
High and low alarms.
Real time clock for date and time stamping of results.
Bluetooth® stored test results transfer to PC.
Advanced memory functionality with download.
Megger PowerDB/PowerDB Lite™ compatible.
