DET14C Earth Resistance Clamp Tester

Megger DET14C Earth Resistance Clamp Tester is a precision tool built for safe, fast, and reliable earth testing without system disconnection. It measures ground resistance in multi-ground installations while maintaining high accuracy and ease of use.

Engineered with flat core ends, Megger DET14C ensures durable, low-maintenance operation. The design reduces dirt build-up and improves contact reliability, delivering consistent readings in demanding environments. Its built-in filter enhances noise immunity, ensuring accurate performance in electrically noisy sites.

Advanced Performance

This instrument measures both ground resistance and true RMS leakage current up to 35 A rms, offering essential data for monitoring earthing system performance. It provides clear readings through its backlit LCD display, enabling use in dimly lit or confined areas. Automatic self-calibration and an auto-ranging feature maintain dependable accuracy with minimal user effort.

Smart Design and Functionality

The elliptical clamp head allows access to cables and straps up to 50 mm wide or 37 mm diameter, ideal for power stations, substations, and communication towers. Megger DET14C includes memory storage for test data and features audible and visual hold indicators for enhanced usability. Its rugged build and ergonomic design make it suitable for long-term professional use across industrial and field applications.

Megger DET14C offers exceptional efficiency for verifying lightning protection systems, assessing earthing at pylons, RF transmitter sites, and other installations where quick and safe measurements are required. With advanced safety protection, intelligent data handling, and simple operation, it represents the next level of resistance testing technology.

Key Features
  • True RMS ground leakage current measurement up to 35 A rms
  • Measures ground resistance from 0.05 Ω to 1500 Ω
