DY4300B 2/3/4 Wire Earth Resistance Soil Resistivity Tester, 0.001Ω-200kΩ High Precision Ground Resistance Meter, Auto/Manual Frequency Selection, 1000 Sets Data Storage

The DY4300B is a high-precision digital earth resistance and soil resistivity tester, specially designed for industrial, electrical and construction ground testing work. Integrating multiple testing modes and intelligent functions, this tester solves the pain points of low accuracy, single function and complex operation of traditional ground resistance meters, providing efficient and reliable testing solutions for various grounding engineering projects. In terms of data management, the built-in 1000 sets of data storage function realizes batch recording of test results, which is convenient for engineering data archiving and subsequent inspection. The automatic calculation function of soil resistivity saves tedious manual calculation steps, greatly improving the overall work efficiency of field testing. Equipped with automatic ranging and high-definition LCD display, the device realizes one-key intelligent measurement with clear and intuitive data display. It is widely used in power grid detection, building lightning protection grounding, mechanical equipment grounding, petroleum chemical engineering, railway engineering, soil survey and other fields, which is an essential professional testing tool for electricians, engineering technicians and maintenance personnel.
