The Megger DET14C and DET24C Digital Earth Clamps are portable tools for clamp-on ground resistance (0.05-1500 Ω) and true RMS leakage current (0.5 mA-35 A rms) measurements in multi-ground systems without disconnection, featuring an elliptical clamp for access to cables up to 37 mm and tapes up to 50 mm.
They offer noise immunity, market-leading accuracy, and CAT IV 600 V safety, with the DET24C adding data logging and Bluetooth. The compact, IP30-rated units (985 g) use 2x AA batteries for 24 hours and operate in -20°C to 50°C.
The kit includes the clamp, calibration loop, batteries, guide, and carry case, with no warranty specified, ideal for safe and efficient ground testing in utility and industrial settings.
