| Description |
Ecology’s Water Quality Program’s standard operating procedure (SOP) for the calibration of a meter capable of measuring pH, and/or oxidation-reduction potential, dissolved oxygen, specific conductivity, and turbidity. The SOP covers meter calibration, sample collection, sample measurements, and quality assurance/quality control procedures to ensure we have the highest data quality. It is not a substitute for the manufacturer’s meters’ user manual; calibration, maintenance, and storage recommendations; or mandatory training required by the manufacturer. This SOP does not substitute for project specific quality assurance documents. |
