Brief introduction
RB-201AtypeCODThe ammonia nitrogen analyzer is an economical model independently developed and produced by our companyCODThe ammonia nitrogen detector, developed according to the documents released by the State Administration of Protection, has accurate and effective measurement results.CODThe closed digestion colorimetric method is used, and the Nessler's reagent colorimetric method is used for ammonia nitrogen.
Scope of application:The instrument is used in environmental testing, sewage treatment, scientific research institutions, and colleges and universities. Suitable for surface water, groundwater, domestic sewage, industrial wastewater and other types of waterCODDetection of ammonia nitrogen.
2、 Detection principle
RB-201AtypeCODAmmonia nitrogen analyzer,CODThe determination of ammonia nitrogen was carried out using the closed catalytic digestion colorimetric method with a digestion tube, and the determination of ammonia nitrogen was carried out using the Nessler's reagent colorimetric method, both of which were from the United StatesEPAAfter recognizing the method, the sample is directly displayed using imported cold light sources, narrowband interference technology, and microcomputer automatic data processingCODValue and ammonia nitrogen value.
