Earth Impedance Tester
Brief Introduction
ZC-FR3010A earth impedance tester is a commonly used meter for measuring grounding resistance.
Features
1. It adapts large-LCD gray screen backlight display and microprocessor technology to meet the requirements of two-wire and three-wire test resistors. It’s a new generation grounding measurement instrument that replaces traditional swing table measurement.
2. Applicable to telecommunications, electric power, meteorology, computer room, oil field, distribution line, iron tower transmission line, gas station, factory ground network, lighting rod, etc. Instrument detection is accurate, fast, simple, stable and reliable.
