Description
Get a clamp-on ground resistance tester to accurately test ground resistance with a measurement range of 0.010Ω to 200Ω. Digital earth tester is suitable for grounding system measurements in power systems, telecommunications, meteorology, oil fields and buildings.
Features
- Digital earth resistance tester is a high-quality ground resistance tester, available with a 32mm clamp and 0.010Ω~200Ω measure range.
- Ground resistance tester is a non-contact measurement, which is safe and fast. When measuring the loop grounding system, there is no need to disconnect the grounding lead and the auxiliary grounding electrode.
- The clamp ground resistance tester can measure ground faults that cannot be measured by traditional methods and is suitable for occasions where traditional methods cannot be used.
- The LCD of the earth testing meter clearly displays the measurement data in high definition, and the data can be displayed in a backlight.

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.
Tips: What is a clamp earth resistance tester?
Clamp earth resistance tester can measure the connection resistance of any looped system without using an auxiliary ground rod or interrupting the grounding of the equipment under test. As long as the ground wire or ground rod is clamped with the clamp head, the ground resistance can be measured safely and quickly. It can also be applied to multiple parallel grounding systems.
