NHNG-3010typeOnline ammonia nitrogen monitoring device
NHNG-3010typeNH3-NThe fully automatic online analyzer is a developed ammonia nitrogen analyzer with completely independent intellectual property rights（NH3-N）Automatic monitoring instrument is an instrument that uses advanced flow injection analysis technology to achieve online analysis of ammonia nitrogen. Capable of long-term unmanned automatic monitoring of various water bodiesNH3-N.
It can measure very low and high concentration ammonia nitrogen, and is suitable for laboratory or on-site online rapid analysis of ammonia nitrogen content in Rivers and Lakes, tap water, discharged wastewater, high concentration sewage and various solutions.
1. Flow injection analysis technology and safe and convenient analysis methods.
2. The unique automatic enrichment function enables the instrument to have a large measurement range:0.05mg/L—1500mg/L
3. The reagent is non-toxic, just diluteNaOHIt can be easily prepared with distilled water containing acid-base indicators. The cost of analyzing each sample is only0.6Splitting money.
4. The unique gas-liquid separator (patented) eliminates the need for cumbersome and expensive pre-treatment devices for samples, eliminating the need for instrument cleaning. It is currently the most simplified instrument among various similar products.
5. .The operating and maintenance costs are extremely low.
6. For ammonia nitrogen concentrations greater than0.2 mg/LThe sample can use ordinary distilled water as the solvent for the reagent, which is convenient to use.
novelThe working principle of the instrument
The peristaltic pump of the instrument delivers and releases liquid (dilute)NaOHSolution is used as the carrier fluid, and the injection valve is rotated according to the set number of times to formNaOHThe solution and water sample are mixed at intervals, and when the mixing belt passes through the separation chamber of the gas-liquid separator, ammonia gas in the sample is released. After passing through the gas-liquid separation membrane, the ammonia gas is received by the liquid（BTBAcid alkali indicator solution) reception, ammonium ions make the solutionpHRising, the color changes from yellow green to blue. After ammonium enrichment, the receiving solution is transported to the flow cell of the colorimeter, and its photoelectric voltage change value is measured to obtain the content of the sampleNH3—NContent.
