Product Description
Measuring COD using digestion tube with closed catalytic digestion colorimetric method, ammonia nitrogen determination using Nessler reagent colorimetry, total phosphorus by closed digestion colorimetric method, both are US EPA approved methods, then use imported cold light source, narrow-band interference technology and microcomputer to process the data, finally the COD, ammonia nitrogen and total phosphorus values of the sample are displayed directly. The instrument is widely used in environmental monitoring, waste water treatment, R&D institutes and colleges and universities.
