Oxidation-Reduction Potential (ORP), sometimes known as redox sensors, measures a solution's ability to act as an oxidizing or reducing agent. The ionic potential data obtained by an ORP probe is crucial for a variety of industrial applications, including evaluating the purity of drinking water, monitoring the anaerobic activity of wastewater, and guaranteeing uniformity in food manufacturing operations like baking.
METTLER TOLEDO manufactures a diverse range of high-quality ORP electrodes for both laboratory and field applications. ORP sensors using silver, platinum, or gold rings can monitor redox potentials in media with a variety of chemical characteristics.
