Principle of nitrate ammonia nitrogen detection in purified water, nitrate nitrogen analyzer

Measuring principle

Using composite measurement techniques to separately measure the concentrations of ammonia nitrogen and nitrate in water samples. Ammonia nitrogen is measured using an ammonia sensitive electrode method, while nitrate is measured using a reagent free ultraviolet absorption method. Nitrate: Continuous spectral scanning of purple visible light (200-720nm), using absorbance at 220/275nm ultraviolet to calculate nitrate concentration. Easy to use, no need for reagents. Ammonia nitrogen: Add sodium hydroxide reagent to adjust the pH value of the sample to>12, and the ammonium ions in the water will be converted into ammonia gas. Use an ammonia sensing electrode to measure and convert the concentration of ammonia nitrogen. Anti chromatic interference, wide measurement range.
