Alternative Name:

Earth resistance tester, dual-clamp resistance tester

 

Product Introduction:

The instrument is a hand-held tester used to measure earth resistance, and to evaluate the grounding quality.

 

Good grounding system is an important guarantee for safety and reliable operation of electronics, telecommunications and other electrical equipment. Earth resistance value is the standard to judge the quality of grounding system. Accurate, fast, simple and reliable earth resistance measuremetnt methods become the urgent need for thunder protection technology field. HYG***0 multifunction dual-clamp earth resistance tester widely applied for telecommunications, electricity, weather, room, power distribution lines, transmission line towers, gas stations, factories grounding grid and lightning rod.
