The Hayward HCC 2000 Controller Package with Pre-Mounted Chemical Feed Pumps is an enhanced water chemistry monitor that is microprocessor based, and uses pH and ORP sensors (Oxidation-Reduction Potential) to monitor water levels and corrects them with a total chemical automation system. This chemistry monitor will ensure rapid deactivation of waterborne pathogens such as E. coli, using already existing chemical feeding equipment. The Controller Package comes with a flow cell, flow sensor, pH and ORP sensors, mounted peristaltic feed pumps for pH and chlorine adjustment and an installation kit. This monitor will work with any size swimming pool, spa or water feature.
