Introduction：

Soil Resistivity Tester also Known as Ground Resistance • Soil Resistivity Tester, Precision Ground Resistance Tester, etc., is a commonly used meter for measuring grounding resistance.
It adopts a large LCD gray-white screen backlight display and microprocessor technology to meet the requirements of two-wire、three-wire and four-wire test resistance and soil resistivity.
Suitable for telecommunications, electricity, meteorology, computer rooms, oil fields, power distribution lines, iron tower transmission lines, gas stations, factory grounding networks, lightning rods and so on. Instrument testing is precise, fast, simple, stable and reliable.
The Soil Resistivity Tester is controlled by the microprocessor and can automatically detect the connection status of each interface and the interference voltage and interference frequency of the ground network, and has the function of testing the auxiliary grounding resistance value.
At the same time store 500 sets of data, resistance measurement range: 0.00Ω ~ 200.00kΩ, grounding voltage range: 0.000 ~ 1000.0V.
Online monitoring data through monitoring software, USB data uploaded to PC and unique features such as intelligent alarm alert
The Soil Resistivity Tester consists of host, monitoring software, test line, USB cable, and grounding rod. It has the functions of reading, checking, saving, reporting and printing of historical data.
