| Abstract: | The problems for application of industrial ORP meter in uranium mill leaching process are easily corroded by acid and alkali, not resisted to high temperature and easily worn by ore abrasion;these problems are solved by the selection of composite ORP electrode. An automatic cleaning device was designed for the sensor electrode to solve the problem of compound ORP electrode scaling which affects the measurement accuracy. The secondary instrument adopts single chip microcomputer technology to realize the intelligent ORP instrument. The improved intelligent ORP meter has been used in uranium mill to guide the industrial production of leaching process. |
