Lightning protection soil resistivity tester

Lightning protection soil resistivity testerIntroduction:

The soil resistivity tester, also known as the grounding resistance soil resistivity tester, precision grounding resistance tester, etc., is a commonly used instrument for testing and measuring grounding resistance. It adopts a large LCD gray white screen backlight display and microprocessor technology to meet the requirements of two, three, and four wire testing of resistance and soil resistivity. Suitable for telecommunications, power, meteorology, computer rooms, oil fields, power distribution lines, iron tower transmission lines, gas stations, factory grounding grids, lightning rods, etc. The instrument testing is characterized by precision, speed, simplicity, stability, and reliability.

The soil resistivity tester is controlled by a microprocessor and can automatically detect the connection status of various interfaces and the interference voltage and frequency of the grounding grid. It also has the function of testing the resistance value of auxiliary grounding electrodes. Simultaneously storing 500 sets of data, resistance measurement range: 0.01 Ω~30.00k Ω, grounding voltage range: 0.01~100.0V. Data can be monitored online through monitoring software, USB data can be uploaded to PC, and it has intelligent alarm prompts and other functions.

The soil resistivity tester consists of a host, monitoring software, testing line, USB cable, and grounding rod, and has functions such as historical data reading, viewing, saving, reporting, and printing
