Products Description
HM2571B is a high-end multifunctional clamp type earth resistance meter. With USB communication interface, storage data can be uploaded to the computer, through software analysis, report, printing and so on.the meter could test 40A leakage current.supports multi-parameter on-screen display function, can display grounding resistance and ground leakage current at the same time, which is more practical, convenient and efficient.
The instrument is widely used in grounding resistance measurement and loop resistance measurement of electric power, telecommunications, meteorology, oil field, construction and industrial electrical equipment. When measuring the grounding system with loop, it is not necessary to disconnect the grounding down conductor, and no need auxiliary electrode, which is safe and fast.
