Product Overview
Description
Description :
ERT-600 color screen intelligent earth grid grounding resistance tester is the latest new generation of intelligent earth grid test products launched in 2020. It adopts the integrated design of the American imported trolley case, convenient on-site movement, intelligent touch LCD large color screen, and automatic digital display , The operation is simpler. The instrument adopts frequency conversion anti-interference technology and does not require high current measurement. It can measure accurate data of 50Hz in a strong interference environment of substations. It can measure ground impedance and ground resistance at the same time. Accuracy is higher. Measurement results are directly displayed and can be more realistically reflected actual characteristics of ground network.
