由国家科委腐蚀学科下达项目,北京钢铁学院、中科院上海冶金研究所、上海电子元件二厂联合研制的FC-5型腐蚀测量仪于最近研制成功。FC-5腐蚀测量仪,可用于极化电阻测量和测试金属材料在弱极化区的极化行为。这种仪器与一般的恒电位仪不同,它采用“恒电位控制电流脉冲”工作方式,因而能理想地消除由于溶液电阻带来的测量误差。仪器工作时分“自动”和“手动”二种状态:“自动”工作状态时,仪器能自动定时补偿开路电位和放大的漂移,并可根据需要自动
Corrosion by the State Science and Technology Commission issued the project, Beijing Institute of Iron and Steel, Chinese Academy of Sciences Shanghai Institute of Metallurgy, Shanghai Institute of electronic components jointly developed FC-5-type corrosion measuring instrument in the recent successful development. The FC-5 corrosion meter can be used to measure polarization resistance and test the polarization behavior of metallic materials in weakly polarized areas. Unlike conventional potentiostats, this instrument uses a “constant current controlled current pulse” mode of operation, which ideally eliminates measurement errors due to solution resistance. Instrument working hours “Auto ” and “Manual ” two states: “Auto ” working state, the instrument can automatically compensate for open-circuit potential and amplified drift, and can be automatically
