| Abstract: | The instrument of determination of weak- dissociation constant based on electrical conductive method was optimized and redesigned in the paper. The improved instrument was characterized by unitization of machine and electron devices, data of voltage determination and electrical resistance collection and intelligence of treating experiment data. It was showed that operation was simple, sensitivity, precision and accuracy was high to the novel instrument. So, it is valuable to be used widely. |
