Nitrite analyzer (900 series) HG-SZ-103H

Product Description, Technical Parameters, and Configuration

The HG-SZ-103H water quality nitrite analyzer is developed and designed based on the authoritative certification method GB7493-87 "Water Quality Nitrite Nitrogen Determination Spectrophotometer" standard. In a phosphoric acid medium with a pH value of 1.8 ± 0.3, nitrite reacts with p-aminobenzenesulfonamide to generate 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.
