The ammonia nitrogen water quality analyzer is specially designed for the water quality analysis of urban and industrial sewage, drinking water, rivers, and groundwater. Using the latest electrochemical analysis technology (ion selective electrode), based on the unique compensation curve obtained from a large number of on-site research data analysis, the introduction of multi-parameter automatic compensation can quickly and accurately measure the ammonia nitrogen concentration in the water to achieve continuous measurement and long-term reliable operation.
