Abstract
The present method and apparatus set forth an improved measuring device and system of measuring to determine hypochlorite concentration from electrolyte discharge from a chlor-alkali cell. In the preferred and illustrated embodiment, a container means suspended at the lower end of a wand captures electrolyte. It enables electrodes to be submerged with the electrolyte to obtain a measurement of the hypochlorite concentration. The electrodes include a current emitting electrode, a reference electrode and a gold sensing electrode having an external surface which is etched to increase the surface area and has a coating of hypochlorite thereon to maintain uniform calibration and measurement during operation.
