The Tekneka GR805 Clamp-on Ground Resistance Tester is a high-precision instrument designed for fast and accurate ground resistance measurements without the need for auxiliary electrodes. It features a measuring range from 0.025Ω to 1500Ω with auto range selection for seamless operation. The 999 LCD with special symbols ensures clear readings, while the overload indicator enhances measurement reliability. Built for safety, it complies with 300V CAT III pollution degree 2 (IEC 61010-1 and IEC 61010-2-032) standards. The device offers a quick measurement time of 0.5 seconds, operates with low power consumption (40mA), and includes a low battery indicator for uninterrupted performance. Ideal for grounding system inspections, electrical safety compliance, and industrial applications, the Tekneka GR805 ensures reliable and hassle-free ground resistance testing.
