Introduction:

Portable Ammonia nitrogen colorimeter is mainly use for rapid test to get the ammonia nitrogen ion concentration in the water, using international standard method.Portable Ammonia nitrogen colorimeter is eco-friendly, the test is fast and the result is accurate.


Ammonia in water is either un-ionized ammonia or the ammonium ion.  Typically, the value reported is the sum of both forms and is reported as total ammonia or simply - ammonia.  The relative proportion of the two forms present in water is highly affected by pH.

Un-ionized ammonia is the toxic form and predominates when pH is high. Ammonium ion is relatively non-toxic and predominates when pH is low. In general, less than 10% of ammonia is in the toxic form when pH is less than 8.0 pH units. This proportion increases dramatically as pH increases.

The equilibrium between NH3 and NH4+ is also affected by temperature. At any pH, more toxic ammonia is present in warmer water than in cooler water.
