Ammonia nitrogen in water refers to ammonia in the form of free ammonia, which mainly comes from the decomposition products of nitrogen-containing organic matter in domestic sewage under the action of microorganisms, industrial wastewater such as coking synthetic ammonia, and farmland drainage. When the ammonia nitrogen content in the water body is high, it is toxic to fish, and it is also harmful to humans to varying degrees. Determination of ammonia nitrogen content in water helps to evaluate water pollution and "self-purification" status, so ammonia nitrogen is an important indicator to characterize water pollution.
Ammonia nitrogen online monitor - performance characteristics of ammonia nitrogen detector
The digestion and colorimetry of the instrument are completed in one body, the structure is simple and reliable, and the possibility of errors is reduced.
Adopt imported modified PTFE transparent hose, the diameter of which is greater than 1.5mm, which reduces the probability of water sample particle blockage.
It can automatically clean the sampling pipe to prevent the formation of algae or biofilm.
After an abnormal reset and power failure, the instrument automatically discharges the residual reactants in the instrument and automatically returns to its working state.
Low failure rate, less maintenance, and less reagent consumption.
Intelligent fault self-diagnosis function, alarm prompt, instrument management, and maintenance are very convenient.
Adopt a multi-channel valve, strong anti-corrosion performance, long service life, safety, and reliability.
