HBZ-100NHAmmonia nitrogen analyzer

Product Description:

The ammonia nitrogen analyzer is available in types A and B according to different testing standards. Among them, type A adopts Nessler's reagent colorimetric method GB7479-87; The B-type adopts the salicylic acid photometric method specified in the national standards GB7148-81 and ISO7150/1-1948 as the basic testing method, supplemented by sample colorimetric reaction pretreatment, to achieve rapid and accurate colorimetric determination of the sample. It has the advantages of stability, sensitivity, reliability, and mercury free.

Applicable standards:GB7479-87； GB7148-81、ISO7150/1-1948

Technical parameters:

1. Measurement range: direct measurement of 0.1mg/L to 20mg/L, dilution measurement of water quality greater than 20mg/L

2. Repetitive error: The ammonia nitrogen concentration ranges from 0.1mg/L to 20mg/L, with an error of ≤± 5%

3. Single measurement time: no more than 15 minutes for sample processing and measurement

4. Environmental temperature: 5～40℃

5. Relative humidity: ≤ 85％

Performance characteristics:

1. Type A machine adopts Nessler's reagent colorimetric method GB/T7479; The B-type machine adopts the salicylic acid photometric method GB/T7418 ISO7150/1-1984。

2. The instrument can produce and store standard colorimetric curves, and adjust the ammonia nitrogen colorimetric curve of water quality according to different water objects.

3. The use of an optical path colorimetric system greatly improves the reliability and stability of the instrument.

4. The B-type machine uses sodium dichloroisothiocyanate instead of sodium chlorate, greatly enhancing the stability and effectiveness of the chlorine containing reagent solution.

5. The B-type machine adopts the * sample processing method to shorten the analysis time.
