The upgraded version of the Megger's DET14C clamp meter, the DET24C is an advanced earth ground measurement tool with dedicated downloadable memory.
Featuring large-size clamping jaws, the DET24C fits around both earth cables and straps up to 50mm. The jaws are eliptical for easy connection and are designed with flat core ends that prevent dirt buildup and ensure measurement accuracy.
This earth tester can test ground resistance accross a range of 0.05 to 1500Ω without the need to disconnect the grounding. It also includes a dedicated true RMS ground leakage current function which can test from 0.5mA to 35A.
By using the built-in memory on this tester, up to 2000 records can be stored and viewed back on the instrument.
