SG3020B+clamp type grounding resistance tester (loop resistance tester) is a new generation of grounding resistance tester developed by the technical team of Shanghai Shenggao Electric Technology Co., Ltd. It adopts a new generation of LCD black screen backlight display and microprocessor technology, Ω+A synchronous display, and measures grounding resistance conveniently and quickly through induction. When measuring grounding systems with loops, there is no need to disconnect the grounding lead or auxiliary electrodes, which is safe and fast.

The SG3020B+clamp type grounding resistance tester is widely used in telecommunications, power, meteorology, computer rooms, oil fields, power distribution lines, iron tower transmission lines, gas stations, factory grounding grids, lightning rods, etc. Instruments have the characteristics of testing, speed, simplicity, stability and reliability. We welcome new and old customers to consult and purchase.
