Description
The online Ammonia Analyzer is using colorimetry as measuring method, a light intensity meter capable of measuring the intensity of light at a specific wavelength to measure the color intensity of sample solutions. The slicylate reacts with chloramines to form 5-aminosalicylate which is oxidize to blue indosalicylate
The system is designed with sampling conditioning systems that collect and filter the sample by step motor pulse control method. It is also equipped with fixed quantity injections with multi-channel valve system ( 7- port distribution purpose
