Product Description

Ammonia nitrogen water quality online automatic monitor Standing cabinet type

Product Overview:

Ammonia nitrogen in water refers to the ammonia present in the form of free ammonia, which is mainly derived from the decomposition products of nitrogenous organic matter subject to microbial action in domestic sewage, industrial wastewater such as coking ammonia synthesis, and farmland drainage. Higher levels of ammonia and nitrogen in water can be toxic to fish and harmful to humans to varying degrees. Determination of ammonia nitrogen in water helps to evaluate the pollution and 'self-purification' status of the water body, so ammonia nitrogen is an important indicator to characterise the pollution of water quality.
The analyser is capable of long-term unattended automatic continuous work according to the site settings, and is widely used in industrial pollutants discharging wastewater, municipal sewage treatment plant wastewater, environmental quality surface water and other occasions. According to the complexity of the field test conditions, optional pre-treatment system to ensure that the test process is reliable, accurate test results, to fully meet the needs of different occasions on-site needs.

Measurement method:
The mixture of water sample, potassium dichromate digestion solution, silver sulfate solution (silver sulfate can be added as a catalyst to oxidise straight-chain fatty compounds more effectively) and concentrated sulfuric acid is heated to 165°C. The dichromate ions oxidise the organics in the solution and the colour changes, and the analyser detects this colour change, and converts this change into a COD value to be outputted, and the amount of dichromate ions consumed is equal to the amount of oxidisable The amount of dichromate ions consumed is equal to the amount of oxidisable organic matter, i.e. COD.
