#NHNG-3010 ONLINE AMMONIA NITROGEN METER

NHNG-3010 online and automatic ammonia nitrogen meter to monitor NH3-N,BOQU has completely independent intellectual property right.it’s the world-class instrument to measure ammonia nitrogen (NH3-N).the working principle is 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, and is released when the mixing belt passes through the separation chamber of the gas-liquid separator. The ammonia gas in the sample is taken out, and the ammonia gas is passed through the gas-liquid separation membrane and then received by the receiving liquid (BTB acid-base indicator solution), and the ammonium ion causes the pH of the solution to rise, and the color changes from yellow-green to blue. The ammonium-enriched receiving solution is sent to the flow cell of the colorimeter, and the photovoltage change value is measured to determine the NH3-N content in the sample.

Main features

Advanced flow injection analysis technology and safe and convenient analytical methods

Unique automatic enrichment function, the instrument has an oversized measuring range: 0.05mg/L-1500mg/L

The 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.
