초록 ▼

An improved method and apparatus for the measurement of amounts of free available chlorine in solution which is independent of the pH have been developed. The apparatus includes a sensing electrode, which is internally buffered and self-cleaning, and a reference electrode supported within a container. A potential measuring means is connected between the electrodes. The solution containing the available chlorine is introduced to the container through an inlet and is released through an outlet. The improvement comprises employing as the sensing electrode a porous conductive material having means for internally supplying a pH control solution. Employing the apparatus, residual amounts of an oxidizing or reducing agent in solution can be continuously measured, independent of the pH of the solution. In addition, the electrode surface is continuously cleansed by the pH control solution. The method and apparatus of the present invention can be used, for example, to measure the free available chlorine concentration in swimming pool waters.
