COD 4700 - CHEMICAL OXYGEN DEMAND ANALYSER

COD 4700 is a chemical oxygen demand analyser which is an analytical instrument used to measure the amount of oxygen required to chemically oxidize organic and inorganic pollutants present in water or wastewater. COD is one of the most important parameters for assessing water quality and the level of pollution in industrial effluents, municipal wastewater, rivers, lakes, and drinking water treatment systems.

A COD analyser provides rapid and continuous monitoring of water contamination, helping industries comply with environmental regulations and optimize treatment processes.
