The Extech 382357 Clamp-On Non-Contact Ground Resistance Tester provides an efficient and safe solution for ground resistance testing without the need for auxiliary spikes. This clamp-on device allows users to perform accurate, non-invasive measurements directly on ground conductors, making it ideal for maintenance professionals and electrical inspectors.
Equipped with True RMS functionality, the tester measures AC leakage currents from as low as 0.2mA up to 30.00A, ensuring precision even in complex electrical environments. The unit features a high-resolution autoranging ground resistance measurement capability from 0.03Ω to 1500Ω with a 0.02Ω resolution.
The Extech 382357 also includes a programmable datalogging feature that stores up to 116 readings, providing a useful historical view of your system’s grounding performance. An integrated Hi/Lo alarm allows for quick identification of abnormal readings. Designed with user-friendliness in mind, the tester offers an ergonomic grip and a clear display for streamlined operation in the field.
