Product Details
YNH-1L ammonia nitrogen analyzer
Equipment Introduction
A single parameter measuring instrument developed according to the domestic water quality situation and regulatory requirements, which conforms to the usage habits of domestic users. It is based on HJ535-20009 "Water Quality? Determination of ammonia nitrogen? The development and design of the "Nessler's reagent spectrophotometric method" standard involves the reaction of ammonia nitrogen in the form of free ammonia or ammonium ions with Nessler's reagent to form a pale yellow brown complex. The absorbance of this complex is proportional to the ammonia nitrogen content, and it is directly displayed as the ammonia nitrogen content (mg/L) after calculation by a microcomputer chip using colorimetric method. The instrument is widely used in environmental monitoring, sewage treatment, scientific research institutions, and colleges and universities.
