Ø Introduction
This product mainly uses Nessler's colorimetric method to measure ammonia nitrogen in water, which has the characteristics of simple operation and high sensitivity. The principle is that the free ammonia and ammonia ions in the form of ammonia nitrogen react with Nessler's reagent to form a yellow brown complex, and the color of the complex is proportional to the content of ammonia nitrogen. The instrument is widely used in surface water and industrial wastewater. Measurement of water quality such as domestic sewage.
