Product Details

Instrument Introduction

The practical nitrite analyzer is developed and designed based on the authoritative detection method GB7493-87 "Determination of Nitrite Nitrogen in Water Quality by Spectrophotometer". It is developed and produced using imported cold light sources and narrowband interference technology, with stable and reliable performance. The display screen adopts a 5-inch LCD high-definition screen, combined with a simple three-step detection program, allowing operators to quickly and accurately detect the concentration of nitrite in water quality.

Detection Principle

In a phosphoric acid medium with a pH value of 1.8 ± 0.3, nitrite reacts with p-aminobenzenesulfonamide to form diazonium salts, which are then coupled with N - (1-naphthyl) - ethylenediamine to form a red dye. The absorbance is measured by spectrophotometry, and the nitrite content (mg/L) is directly displayed after processing and calculation by a microcomputer chip.
