This instrument uses Nessler's colorimetry to measure ammonia nitrogen in water. The method is simple and sensitive. The principle is that ammonia nitrogen in the form of free ammonia or ammonium ions reacts with sodium 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 drinking water, groundwater, surface water, municipal sewage, industrial sewage, environmental monitoring, colleges and universities, scientific research institutions and other fields water measurements.
