Water can have a positive or negative Oxidation Reduction Potential (ORP) and it is measured in volts. ORP is a way to measure water’s ability to accept or release electrons during a chemical reaction. Understanding the ORP value helps determine the quality of the water and thereby helps operators decide what water treatment processes may be required. The more positive the ORP value, the greater the tendency the water has to oxidise (gain electrons from) organisms or other material in the water, thereby killing or destroying them.
ORAKEL ORP sensors measure the redox potential of any aqueous solution. They are platinum-based sensors with integral reference electrodes which use no reagents, are extremely stable and have reduced maintenance and lower whole-life costs.
