Development and Application of Portable Soil Corrosion Meter

The common methods to evaluate the soil corrosion are test of buried specimen and analysis method of soil physical and chemical properties, these methods take long period, are laborious, sometimes lead unsuitable conclusion. The portable soil corrosion meter developed based on the basis of polorized resistance, its application results suggested that the soil with low corrosion can de classified two classes of quantitative index based on corrosion, current density.
