Abstract
An amperometric bromine control system accurately maintains a desired concentration of bromine within a home spa or in other water features. The control system employs amperometric sensing to measure the bromine concentration in the spa water and uses this measurement to control the electrochemical production of bromine through the oxidation of aqueous bromide. The level of bromide in the spa water desirably is greater than 50 ppm in order to obtain a linear relationship between the current level sensed through the amperometric measurement and the concentration level of bromine in the water. In this manner, the control system can accurately measure the bromine concentration in the spa water and precisely maintain the bromine concentration within a desired range between about 2 ppm and 6 ppm.
