Product Description

This COD(Chemical Oxygen Demand) analyzer measures the amount of oxygen required for oxidation of organic contaminants in water, which is converted to Carbon dioxide and water. Organic contamination is calculated by the amount of consumed oxide after the oxide is added to the sample, heated and oxidized.

Product Feature

–Low price –5-port control valve •Simple composition •Low reagents consumption –Stable and accurate measurement –Easy operation –On-line measurement –Data transmission via 4~20, RS-232, TCP/IP
