XHAN-91B Automatic Ammonia Nitrogen Monitor

   This device is designed based on the sequential injection technique. For this monitoring, national standard method and multiple-way valve switching are adopted, to sequentially and quantitatively inject the water sample and reagent into the digestion tube for constant temperature reaction, and then into the colorimetric detection module for measurement. It is widely used for continuous monitoring of ammonia nitrogen in surface waters like river, lake and reservoir, as well as sewage and industrial wastewater.
