Brand: Erun environmental protection
Name: Laboratory bench-top total nitrogen (TN) water quality analyzer
Model number：ERUN-ST-TN711A
Parameters:Total Nitrogen TN(The ultraviolet method)
Erun environmental protection development and production of laboratory bench laboratory bench total nitrogen water quality detector ERUN-ST-TN711A using ultraviolet method of water ammonia content, the method detection principle is through water inorganic nitrogen and organic nitrogen by potassium persulfate oxidation digestion to nitrate, in sulfate and phosphate acid medium, nitrate and 2,6-dimethyl reaction to produce 4-nitrate-2-6-xycresol and color, then after digestion using laboratory bench total nitrogen water quality detector for colorimetric detection.
