CorrTest Instruments Co. (China) manufactured her first full-digital potentiostat/galvanostat for corrosion electrochemistry in 1995. After 29 years of research and development, CorrTest has developed a series of electrochemical workstations dedicated to electroanalysis, corrosion, electrocatalysis, energy material research, sensors, electrodeposition etc. CorrTest has registered CorrTest^® trademark and acquired a number of patents, software copyrights.

CorrTest has also developed different kinds of corrosion sensors and meters, corrosion management networks for on-site corrosion monitoring and risk evaluation of oilfields, petrochemicals, construction and offshore wind farms.

“Quality from Technology", "Progess from Profession" is our motto for research and development. CorrTest will continue to provide customers with high-quality products and professional services.
