The Megger DET14C represents a new generation of earth ground clamp-on resistance testers. This instrument induces a test current into earth systems and measures ground resistance in multi ground installations without needing to disconnect the ground. It offers market leading access, advanced features, simple operation and CAT IV 600 V safety protection
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. In electrically noisy environments the built-in filter function offers increased noise immunity.
