Introduction

Brand: Erun environmental protection

Name: Laboratory bench-top total nitrogen (TN) water quality analyzer

Model number:ERUN-ST-TN711B

Parameters:Total Nitrogen TN(Achromatic acid spectrophotometry)

Erun environmental protection research and development, production of laboratory bench bench total nitrogen water quality detector ERUN-ST-TN711A using ultraviolet method of ammonia nitrogen content, the method detection principle is through the water inorganic nitrogen and organic nitrogen by potassium persulfate oxidation digestion to nitrate, digestion added sodium metabulfite to remove halogen oxidation interference, in the sulfuric acid and phosphoric acid medium, nitrate and sodium change acid reaction to form yellow complex, after digestion, then use total nitrogen water quality detector ERUN-ST-TN711A test at 420nm wavelength.
