PhotoTek 6000 Phosphate Water Quality Online Automatic Monitor is a new generation of water quality fully automatic online monitor independently developed by Langshi, combining advanced instrument manufacturing technology and dual light path detection technology at home and abroad.

Working principle

The instrument analysis method adopts potassium persulfate oxidation-molybdic acidAmmonium spectrophotometric method. In an acidic medium, orthophosphate reacts with ammonium molybdate to form phosphomolybdic acid in the presence of antimony salt, which is immediately reduced by ascorbic acid to form a blue complex. At the same time, the test results are consistent with the national standard "Marine Monitoring Specification"4 Part: Analysis of Seawater（GB17378.4-1998）And the "Standard Test Methods for Drinking Water without Mechanical Non Metallic Indicators"（GB 5750.5-2006）Matching ensures the accuracy and effectiveness of monitoring.
