NH-4N Precise Ammonia-Nitrogen Analyzer

Brand:NANBEI

Model:NH-4N

Application:

product details

 Principle:

The instrument adopts the NH3-N reaction of Nessler's reagent and  dissociative NH3 or Ammonium ion generates yellow-brown complex. The NH3-N concentration will be calculated by the single-chip computer and the optical colorimetry as the complex color depth is proportional with the concentration of NH3s-N. It’s widely used in the measurement of surface water, industrial waste water and sewage.
