Overview
Nitrate nitrogen analyzer (print type) HG-SZ-701
Product Details
Product Description, Technical Parameters, and Configuration
Detection principle:
The HG-SZ-701 nitrate nitrogen analyzer is designed according to the "Chromogenic Acid Luminescence Method". Under strong acidic conditions, nitrate nitrogen in the water sample reacts with the color reagent to form a brownish yellow complex. Its absorbance is measured by spectrophotometry at a wavelength of 420nm, and after processing and calculation by a microcomputer chip, the nitrite content (mg/L) is directly displayed.
