Megger DET24C Bluetooth Clamp-On Earth Tester

The DET14C and DET24C represent 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. They offer market leading access, advanced features, simple operation and CAT IV 600 V safety protection.
