Production of fully automatic nitrite water quality monitoring instrument

Measurement principle:

Adopting laboratory standard methods《Determination of p-aminobenzenesulfonic acid-naphthylamine by spectrophotometric method》Nitrite in water（NO^2-）Ions andSulfonamide undergoes a chemical reaction to form a diazonium salt solution, which then reacts with a solution of naphthylethylenediamine hydrochloride to form azo dyes. The resulting azo dyes exhibit characteristic absorption at 550nm light. Using Lambert Beer's law to obtain the concentration of nitrite ions.

Instrument features:

Imported long-range fiber pool, anti pollution, maintenance cycle can reach more than 6 months, detection limit can reach 2ppt;

Automatic degassing system eliminates bubbles in the reaction solution, making the measurement more continuous and accurate;

Touch screen control: more convenient operation;

Timed zero calibration;

Application fields:

Drinking water, sources of water pollution, marine water quality, river cross-sections, etc
