TP-300 In Situ Total Phosphorus Analyzer

The detection principle of TP-300 in-situ total phosphorus analyzer is mainly based on spectrophotometry and improved on this basis: the water sample reacts with potassium persulfate in the digestion tank at 120-124 ℃, so that different forms of phosphorus-containing compounds in the water are reacted. converted to orthophosphate. Orthophosphate reacts with ammonium molybdate to form phosphomolybdate heteropolyacid in the presence of antimony salt, which is immediately reduced by ascorbic acid to form a blue complex. In situ sensor suitable for the determination of total phosphorus concentration in water bodies such as surface water, nearshore and estuaries. Through the online monitoring of total phosphorus in water, the instrument can provide users with continuous and stable monitoring data required for water quality investigation and research, water environment monitoring, and early warning of ecological disasters such as red tide and green tide. Product advantages Ammonium molybdate spectrophotometry using the national standard method Small size, submerged installation, in-situ water quality monitoring Unique and compact structure design, low reagent consumption, low operation and maintenance cost Precise optical system, high detection accuracy and good stability Good correlation with manual analysis, suitable for sewage outfall and various water environment monitoring It can be integrated into buoys, multi-parameter monitoring systems, or run on ships, shore-based deployment, etc.
