Details

Applications

RDDLZ provides earth resistance testers with a measurement range of 0.00Ω-300kWΩ, which are widely used in ground resistance measurement and loop resistance measurement in fields such as electric power, telecommunications, meteorology, oil fields, construction, and industrial electrical equipment. When measuring the grounding system with a loop, the ground resistance tester does not need auxiliary electrodes and does not need to disconnect the grounding wire, which is safer and faster.

Tips: Do we need to test soil resistivity regularly?

It depends on whether your current or future needs require soil resistivity testing as it will determine the type of ground resistance tester you need. For example, if your work involves the design or installation of a new grounding system, soil resistivity testing is a must. Currently, most people use a ground resistance tester to test soil resistivity.
