Uniphos Online COD Analyzer
(Potentiometric Method)
Chemical Oxygen demand is defined as the amount of oxygen required for the oxidation of all the organic compounds present in a water sample.
The Uniphos online COD analyzer is a programmable, fully automatic analyzer which measures COD of waste / effluent water samples using a direct method of analysis. This direct method involves oxidation of sample by potassium dichromate and measurement by potentiometric titration. No human intervention is required during the measurement, as the analyzer is completely automated.
The inbuilt diagnostics feature gives an alarm if there are any faulty components or if the reagent level goes below the minimum level. Equipped with a next generation touchscreen HMI for display and programming, the analyzer provides a variety of data communication options such as RS-485 MODBUS and industry standard 4-20 mA analog output
