Clamp earth resistance tester details

Applications

ATO provides earth resistance testers with a measurement range of 0.00Ω-300kΩ, 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.

Clamp earth resistance tester applicationsTips: Why use a clamp earth resistance tester?

The clamp earth resistance meter can measure ground faults that cannot be measured by traditional methods and can be applied to occasions that cannot be measured by traditional methods. It is a major breakthrough in traditional ground resistance measurement technology and is widely used in electric power, telecommunications, meteorology, oil fields, construction and ground resistance measurement of industrial electrical equipment.
