Problems solved by technology

[0003] The existing measuring device of streaming potential on the surface of membrane has the following disadvantages: 1. The test solution flows in one direction and cannot be circulated. The continuous test needs to constantly replenish the solution, which is inefficient and troublesome to operate; 2. The measuring device is easily disturbed by the rotation of the pump. Less Accuracy and Precision
