China Ammonia Nitrogen Water Quality Online Automatic Analyzer

Ammonia Nitrogen(NH3) Water Quality online Automatic Analyzer

Product description
Ammonia nitrogen in water refers to ammonia in the form of free ammonia, which mainly comes from decomposition products of nitrogen-containing organic matter in domestic sewage by microorganisms, industrial wastewater such as coking synthetic ammonia, and farmland drainage. When the content of ammonia nitrogen in water is high, it is toxic to fish and harmful to human beings in varying degrees. The determination of ammonia nitrogen content in water is helpful to evaluate the pollution and self-purification of water, so ammonia nitrogen is an important indicator of water pollution.
The DG-NHNG-3010 online and automatic ammonia nitrogen meter/analyzer can work automatically and continuously for a long time without attendance according to the site settings. It is widely used in industrial pollution source discharge wastewater, municipal sewage treatment plant wastewater, environmental quality surface water and other occasions. According to the complexity of site test conditions, the corresponding pretreatment system can be selected to ensure the test process is reliable,test results are accurate, and fully meet the needs of different occasions.

The recommend temperature is +5~28ºC;humidity≤90%(no dew)PowerAC220±10% V,50±10% Hz,5 A;Dimension sizeHeight 1450xWidth510xLength 450 mm;Data savedThe data can be saved when abnormal alarms and power off.DisplayTouch screen and Command InputOtherWhen Reset after abnormal alarm and power on after off, the instrument automatically discharges residual reactants in the instrument and automatically resumes working status.

MAIN FEATURESAdvanced flow injection analysis technology and safe and convenient analytical methodsUnique automatic enrichment function, the instrument has an oversized measuring range: 0.05mg/L-1500mg/LThe reagent is non-toxic, just dilute NaOH and distilled water with acid-base indicator, which can be easily prepared.The unique gas-liquid separator (patented) eliminates the cumbersome and expensive pre-treatment unit and eliminates the need to clean the instrument. It is the most simplified instrument of its kind.HNG-3010 online ammonia nitrogen meter(NH3-N) automatic run,automatic calibration,few maintenance.For samples with an ammonia nitrogen concentration greater than 0.2 mg/L, ordinary distilled water can be used as a solvent for the reagents, which is convenient to use.
