Introduction: Multi-functional soil erosion rate measuring instrument design is based on the principle of linear polarization, weak polarization measurement of soil corrosion current density method to evaluate soil corrosion. At the same time, using electrochemical method to measure soil corrosivity, the parameters of soil temperature, resistivity, redox potential and so on were also determined by adding thermal element and four-electrode system. Multi-functional soil erosion rate measuring instrument is suitable for soil corrosion assessment, pipeline transportation, urban underground pipeline corrosion assessment, concrete corrosion assessment, as well as the corrosive evaluation of aqueous corrosion medium.
