Abstract
A device for measuring free acid concentrations in a solution bearing an ionic constituent therein, forms a test sample of the solution and measures the concentration of the ionic constituent in solution in the test sample. The device measures conductivity of the test sample and calculates the concentration of free acid in the test sample based on the conductivity and the concentration of the ionic constituent in solution.
