Chemical Oxygen Demand (COD)

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.

We can order the full range of chemical oxygen demand tests from Lovibond and Palintest.  

Please note these products are classed as hazardous for transportation and therefore incur higher postage charges.
