Product introduction of total phosphorus water quality analyzer
The total phosphorus water quality analyzer is specially designed for the monitoring of water quality discharge from pollution sources, and is especially suitable for the online monitoring of low-concentration ammonia nitrogen at the outlet of factories and mining enterprises and urban sewage treatment plants.
Polyphosphate and other phosphide in water are hydrolyzed under acidic conditions at high temperature and high pressure to form phosphate; For other phosphorus compounds that are difficult to oxidize, they are oxidized to phosphate by the strong oxidant sodium persulfate. In the acidic medium, orthophosphate reacts with ammonium molybdate, potassium antimony tartrate to generate phosphormolybdenum heteropolyacid compound, this compound is reduced to blue phosphomolybdate by ascorbic acid, the shade of color is proportional to the phosphorus content in the sample, and the absorbance value of the reaction product is measured by photometry, so as to obtain the phosphorus
Features of total phosphorus water quality analyzer
• The repeatability of total phosphorus measurement values reaches within 3%, and the accuracy is within 5%. The total phosphorus has multiple range automatic switching;
• It can realize user feedback control platform, with users installing the device control software on their computers;
• It has printing functionality and can connect to a printer;
• It has a large data storage capacity, achieving the preservation of historical data for no less than 5 years;
• An automatic leak alarm function is in place, where the instrument automatically alarms when reagent leakage occurs, prompting users for maintenance;
• It adopts optical measurement signal automatic recognition function;
• The maintenance of chemical reagents is simplified and made convenient, requiring reagent replacement once a month;
• The instrument can be updated and upgraded with a one-click USB drive software;
• The ARM system allows for broader application of device functionality.
