China Industry Online Ammonia Nitrogen Monitor for Water Quality

Industry online Ammonia Nitrogen Monitor for Water Quality

Product description
DG-NHNG-3010 online and automatic ammonia nitrogen meter to monitor NH3-N, Jiangsu Degao IoT Technology Co.,Ltd has completely independent intellectual property right, it's the world-class instrument to measure ammonia nitrogen (NH3-N). The working principle is that the peristaltic pump of the instrument delivers the release liquid (diluted NaOH solution) as the carrier fluid, and the injection valve rotates according to the set number of times to form a mixture of the NaOH solution and the water sample at intervals. The ammonia gas in the sample is released when the mixing zone passes through the separation chamber of the gas-liquid separator, and the ammonia gas is received by the receiving solution (BTB acid-base indicator solution) after passing through the gas-liquid separation membrane. The ammonium ions increase the pH of the solution and the color changes from yellow-green to blue. The ammonium-enriched receiving solution is transported to the flow cell of the colorimeter, and the photovoltage change value is measured to obtain the NH3-N content in the sample.

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.
