| Abstract：In this article, the principle, accuracy, advantages and disadvantages for each kind of solution concentration measurement technique were discussed and compared in detail. According to the comparison, it could be found that during crystallization process of strong electrolyte solution, densimeter is available to acquire the on-line concentration data with good accuracy and can be used in future modeling identification and parameter estimation. |
