Key Features
- The standard potassium dichromate method (DIN 38409 H41-H44) dominates the market. It is also available in a modified form as cuvette tests (DIN ISO 15705:2003). Here, potassium dichromate is used as an oxidising agent, silver sulphate as a catalyst, as well as sulphuric acid. Mercuric chloride is also used to mask chloride interferences. This risky chemical cocktail is heated after the aqueous sample has been added, and then simmered for approx. two hours. The oxygen demand is calculated from the concentration of residual dichromate.
Product Details
Chemical oxygen demand (COD) is one ofthe most important sum parameters in wateranalysis. It is considered as a reference forthe organic load of waste water, both in theindustrial and municipal sectors. In general,analytical processes are based on the useof different reagents. However, the safe andenvironmentally friendly procedure is thermaloxidation.Thermal Combustion1-100mg/l, upto 10,000mg/l230 VAC, 50/60 HzResponse Time 3 minutesSteel, IP 54, Powder Coated
