| Abstract: | This paper presents the theory,design and application of a on line ion concentration measuring system,which is provided with a double beam measuring technique.The system originally uses the dual LED in serial as a light source and SPD as a sensor,thus being able to keep the ion concentration under on line detection for a long time.The system is high accuracy with low cost and capable of working continuously.No similar design has been reported at home and abroad. |
