Chemical Oxygen Demand (COD) is a measure of the organic material in a sample that is oxidised by a strong oxidising agent. It is used to measure the number of pollutants in a water sample. High COD levels are harmful to aquatic organisms, so it is essential to monitor the COD levels, particularly at wastewater treatment plants and in agricultural wastewater.

 

COD can be measured by photometry, and Hanna offer a wide range of bench Photometers that are ideal for determining COD levels.
