What is the Megger DET14C Digital Earth Clamp Tester?
The Megger DET14C digital earth clamp tester is a professional clamp-on ground resistance tester designed for UK electricians and electrical engineers carrying out earthing verification, lightning protection testing and maintenance inspections. With a large jaw design and CAT IV 600V safety rating, it enables safe and accurate testing of earth systems without disconnecting the circuit.
Ideal for professionals searching for earth clamp testers, ground resistance meters or earthing test equipment in the UK, the DET14C delivers fast, reliable results in multi-ground installations.
How does the DET14C improve earthing tests on site?
The DET14C uses stakeless measurement technology to induce a test current into the earth loop and measure resistance without breaking the connection, saving time and reducing disruption.
Its large elliptical jaw allows clamping around earth tapes up to 50 mm and cables up to 37 mm, improving access in tight or complex installations.
True RMS current measurement from 0.5 mA to 35 A allows safe detection of earth leakage currents, helping identify faults before disconnection risks occur. A built-in noise filter ensures stable readings in electrically noisy environments, while improved battery life supports extended field use.
The backlit display and audible hold function make operation easier in low-light or restricted areas, and onboard memory allows results to be stored and recalled when needed.
