Soil corrosion tester

Instrument characteristics

Based on years of experience in field testing of soil corrosion and protection, this tester has redesigned and combined thirty types and fifty-six types of instruments, electrodes, reagents, tools, etc. required to make them smaller and in a ready to use working state. They are assembled in two small test boxes. Easy to carry to the field, complete on-site analysis and testing of ten projects related to soil corrosion and protection. The method is reasonable, the data is reliable, flexible and convenient.

Application scope

This tester is suitable for testing and accumulating basic data of material soil corrosion tests, surveying soil corrosion environments, investigating the corrosion status of underground metal components, and diagnosing the causes of corrosion perforation in underground oil and gas pipelines and cables. Except for the second and third projects, the other eight projects can also be used for in-situ determination of soil physical and chemical properties at various field stations. This instrument has been widely used in major oil fields, oil and gas companies, steel, energy, telecommunications, urban construction, national defense and other departments across the country.
