PRODUCT INTRODUCTION
LSPEC 7000 Portable water Quality COD analyzer is a differential UV-vis spectrum absorption technology for the detection of COD and NTU content in municipal sewage, domestic sewage and pollution source outfall. It adopts UV-visible differential absorption method. Compared with COD measuring instrument commonly used chemical titration method, it has the advantages of fast measurement speed, high detection accuracy, no secondary pollution, no interference from chloride ions and no maintenance. It can be widely used in surface water, river water, waterworks, municipal water supply and drainage, industrial sewage and other fields.
