Brief introduction
RB-301AtypeCODThe ammonia nitrogen total phosphorus detector is a printed type independently developed by Ruibin TechnologycodAmmonia nitrogen total phosphorus analyzer integrated machine, this instrument can simultaneously measurecodThe three parameters of ammonia nitrogen and total phosphorus combine advantages and are laboratory testscodEssential instruments for ammonia nitrogen and total phosphorus.
scope of application:Suitable for industrial wastewater, domestic sewage, etccodDetermination of ammonia nitrogen and total phosphorus content.The instrument is used in environmental testing, sewage treatment, scientific research institutions, and colleges and universities.
2、 Detection principle
RB-301AtypeCODAmmonia nitrogen and total phosphorusTester,CODThe determination of ammonia nitrogen was carried out using the Nessler's reagent colorimetric method, while the determination of total phosphorus was carried out using the closed digestion colorimetric method, all 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 processingCODAmmonia nitrogen and total phosphorus values.
