Wuhan GDMK Electric Co., Ltd.

Product description:

Ground continuity tester is the connecting part of power equipment and grounding gird, during long time run of power equipment, Connection is likely due to moisture and other factors, node corrosion, even fracture phenomenon, lead to lead off the assembly line and the main grounding grid connection point resistance increase, there is no security risk in the operation of the equipment, serious when will cause the equipment to run away from the grounding grid.
