Precision Cod Digestion System

We manufacture, supply and trade a wide range of Precision COD Digestion System for our honored clients. It is made to estimate Chemical Oxygen Demand of water / waste water samples. It is based on the APHA Method wherein sample is digested with potassium dichromate and sulfuric acid at 150⁰C in a refluxing assembly to determine the pollution load by measuring the amount of oxygen required for oxidization and convert the organic waste into carbon dioxide and water. Precision COD Digestion System incorporates an aluminum block heater with holes to accommodate C. O. D. reaction tubes of 40mm dia x 200mm length made of heat resistant borosilicate glass.
