ORP Field Measurements Reporting Redox Potential (Eh) Correctly

Many practitioners are familiar with using multiparameter water quality meters in the field which incorporate ORP (oxygen-reduction potential) sensors. But ORP measurements are often reported from field probe measurements without the necessary conversion made to standardize readings to a common reference. Most manufacturers, including In-Situ, use a silver/silver chloride (Ag/AgCl) electrode in potassium chloride (KCl) … Continued
