Brief introduction
RB-301BportableCODThe ammonia nitrogen total phosphorus analyzer is a simultaneous measurement instrument independently developed and produced by our companyCODA portable all-in-one machine with three parameters of ammonia nitrogen and total phosphorus. The instrument is equipped with a rechargeable battery, which can meet the needs of users for outdoor use and is easy to carry.
Scope of application:Applied to environmental monitoring, 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 and total phosphorus.
2、 Detection principle:
RB-301BportableCODAmmonia nitrogen total phosphorus analyzer,CODThe determination of ammonia nitrogen was carried out using the Nessler's reagent colorimetric method, and the total phosphorus was determined 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.
