TR-308 COD ammonia nitrogen total phosphorus analyzer

Detection principle:

The TR-308 COD ammonia nitrogen total phosphorus analyzer from Tongao brand uses a digestion tube closed catalytic digestion colorimetric method for COD determination, Nessler's reagent colorimetric method for ammonia nitrogen determination, and closed digestion colorimetric method for total phosphorus determination, all of which are recognized by the US EPA. After importing cold light sources, narrowband interference technology, and microcomputer automatic data processing, the COD, ammonia nitrogen, and total phosphorus values of the sample are directly displayed. The instrument is widely used in environmental monitoring, sewage treatment, scientific research institutions, and colleges and universities.
