A water system ORP monitor and/or control method to monitor and/or control ORP of a water system, wherein the ORP and pH of the water system are measured, a measured ORP value is corrected to an ORP value at standard conditions on the basis of a preset correction equation that is based on measured ORP and pH values, and the ORP of the water system is monitored and/or controlled on the basis of the corrected ORP value. The corrected ORP value is calculated from the measured ORP and pH values on the basis of the following equation. Corrected ORP value (mV) = measured ORP value (mV) − 59 × (7 − measured pH value)
