Earth Resistance Tester

The Earth Resistance Tester, also known as a double clamp grounding resistance tester, incorporates advanced measurement methods. In addition to the traditional function of measuring grounding resistance with auxiliary grounding, it uniquely allows measurement without an auxiliary ground. The tester features a large LCD gray screen with backlight display and employs microprocessor technology. It offers precision measurement through the controlled selection of the 4-wire method, 3-wire method, simple 2-wire method, and double clamp method.

With its large-diameter current clamp design and double jaw measurement technology, the tester can perform online measurements without the need for auxiliary grounding or isolating the grounding body from the equipment. It is suitable for a wide range of applications, including telecommunications, electricity, meteorology, computer rooms, oil fields, power distribution lines, iron tower transmission lines, gas stations, and factory grounding networks.The instrument is precise, fast, simple to use, stable, and reliable.
