Work KDB-100NH ammonia analyzer according to the different testing standards, there are A, B type. One-A colorimetric method using Nessler reagent GB7479-87; B-type with the national standard GB7148-81 and the norms of international ISO7150/1-1948 acid photometric test as the basic means of colorimetric reaction supplemented with sample pretreatment, samples to achieve rapid and accurate colorimetric assay, with a stable, sensitive, reliable, and do not contain mercury and other advantages. 

 Technical Features 1. Apparatus the use of national standards: ammonia acid colorimetry to complete water quality measurements, the use of international standards norms of sodium dichloroisocyanurate three isocyanate to replace the commonly used sodium hypochlorite, the reagent solution greatly enhanced stability and effectiveness of chlorine (B). 
 2. Equipment can be a standard colorimetric curve of production, storage, and or objects according to different water ammonia water than the color curve adjustment. 
 3. Colorimetry using a unique optical system of the instrument reliability, stability has greatly improved. 
 4. A unique sample handling, the premise of the analysis results are accurate, the shorter analysis time (B).
