The FR2000+ Clamp Ground Resistance Tester is a next-gen tester designed for fast, safe, and accurate ground loop measurements—without auxiliary electrodes or disconnections. Using mutual induction principles, this instrument is ideal for busy industrial or substation environments with grounded loop systems. The black screen display is engineered for daylight readability, while anti-interference filtering ensures stable readings in real-world conditions. Suitable for professionals in energy, telecom, construction, and utility fields.
