White Paper: The Role Of Dissolved Oxygen And ORP Measurements In Power Plant Chemistry

By Mettler-Toledo Thornton, Inc.

ORP (oxidation reduction or redox potential) and DO (dissolved oxygen) measurements can provide valuable information in makeup water treatment, cycle chemistry control and stator coolant. Taking the time to understand the principles of operation of these sensors is a worthwhile effort to help specify appropriate equipment and to obtain successful results with it. This discussion describes the various applications for DO and ORP measurements in power plants. It then provides detail on the significance of these measurements and operation of the sensors.
