Small – Strong – Smart. Reliable COD analysis COD levels play a major role in assessing communal and industrial waste water. As a sum parameter indicating the organic load of waste water, COD is one of the most important parameters in waste water analysis. Among others, COD values are used to calculate and monitor the purification capacities of waste water plants. The new version G of the compact photometer PF-3 and its 3 wave lengths are specifically designed for COD analysis. It is ideally suited for mobile use directly at the place of sampling. Together with the user friendly NANOCOLOR® tests, you can obtain information on the COD content quickly and easily. NANOCOLOR® tube test and the PF-3 allow a complete COD determination between 2–60000 mg/L.
