Earth Continuity Test

Type: ZCDT-10A
       The power industry standard DL/T475-2006 "Guide to Measurement of Characteristic Parameters of Grounding Devices" stipulates that the conductivity should be measured by special instruments. The instrument resolution is 1 mΩ; the accuracy is not less than 1.0. On this basis, our company designed this highly automated and portable tester. It is specifically used to test the electrical integrity of the grounding device; the technical indicators meet or exceed the relevant standards. The instrument is simple in operation, high in precision, fast in test speed, good in reproducibility and intuitive in reading. It is an ideal special instrument that meets the requirements of regulations and standards.
