The Megger DET14C represents a new generation of earth / ground clamp-on resistance testers. These instruments induce a test current into earth systems and measure ground resistance in multi-ground installations without needing to disconnect the ground.

Designed with flat core ends they prevent dirt build up, ensuring measurement integrity and improved reliability over products with interlocking teeth. Other enhancements over current generation products include improved accuracy and up to 300% increase in battery life.

The DET is rugged, compact and has configurable audible alarms. Additional features include a configurable auto shutdown, data storage, self-calibration on power up and a calibration loop - all contained in a sturdy Megger carry case.
