Product details

Online ammonia nitrogen detector in water


Ammonia nitrogen in water refers to the ammonia present in the form of free ammonia, mainly derived from the decomposition products of nitrogen-containing organic matter in domestic sewage by microbial action, industrial wastewater such as coking and synthesis of ammonia, and agricultural drainage. When the ammonia nitrogen content in water is high, it exhibits toxic effects on fish and poses varying degrees of harm to humans. The determination of ammonia nitrogen content in water is helpful in evaluating the pollution and "self purification" status of water bodies, therefore ammonia nitrogen is an important indicator for characterizing water quality pollution.
