CHNH-812 Portable Ammonia Nitrogen Analyzer Water Quality Analyzer Manufacturer Direct Sales Quality Assurance

Product description: This instrument uses Nessler's colorimetric method to measure ammonia nitrogen in water. This method has the characteristics of easy operation and high sensitivity. The principle is that ammonia nitrogen, which exists 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.
