In situ total nitrogen water quality analyzer
The detection principle of AMT/TN-300 type in situ total nitrogen water quality analyzer is mainly based on potassium persulfate oxidation of a hydroquinone spectrophotometry and improved on this basis: Under the condition of alkaline medium at 120~124℃, the ammonia nitrogen and nitrite nitrogen in the sample can be oxidized to nitrate by using potassium persulfate as oxidant, and most of the organic nitrogen compounds in the sample can be oxidized to nitrate. The nitro compound produced by nitrate ion and resorcinol in concentrated sulfuric acid medium is light yellow. AMT/ TN-300 in situ total nitrogen water quality analyzer is an in situ analyzer suitable for the determination of total nitrogen concentration in surface water, inshore water and estuaries. Through online monitoring of total nitrogen in water, the instrument can provide users with continuous and stable monitoring data needed for water quality investigation, water environment monitoring and ecological disaster early warning.
Low power consumption design, can be installed in the buoy system for long-term continuous measurement;
Micro sequential injection system, digestion and testing process requires very little water sample;
Small reagent consumption, long maintenance cycle;
There is an early warning function in the process of digestion heating, and alarm information is sent when the digestion process is abnormal.
Wet chemical detection based on national standard;
Quick disassembly reagent bin design, easy to change reagents;
The average operating power is less than 20W;
Can be submerged 5 meters underwater for in-situ water quality monitoring;
Widely used: in situ, online monitoring, on-site rapid determination, emergency monitoring, groundwater monitoring, external power supply can also be built-in battery.
