Wall-mounted Ammonia Nitrogen Analyzer
Product IntroductionThe online ammonia nitrogen analyzer is a precision instrument mainly used to detect ammonium ions in liquids. There is a layer of ammonium ion selective membrane at the front end of the sensor. When the sensor is placed in the measured solution, ammonium ions in the measured solution enter the interior of the sensor through the selective membrane, forming a tiny potential difference with the reference electrode. The magnitude of the potential difference is proportional to the concentration of ammonium ions. The circuit amplifies the potential difference, so as to obtain the concentration of ammonium ions and calculate the content of nitrogen element.
