Method and apparatus for determining the CaCO3 content in a wash liquid

摘要

A process determines the calcium carbonate content in a sample volume of washing solution drawn from the process and introduced to a measuring cell, followed by dosed admixture of HCl to the cell and a pre-determined reaction time. A measurement is made of the fluid pH, and a detrmination made of the CaCO 3 based on the change in pH value. also claimed is a commensurate pH test assembly.
