TR-208 CODAmmonia nitrogen analyzer

Detection principle:

The TR-208 COD ammonia nitrogen rapid analyzer from Tongao brand uses a closed catalytic digestion colorimetric method for COD determination and a Nessler's reagent colorimetric method for ammonia nitrogen determination, both of which are recognized by the US EPA. After importing cold light sources, narrowband interference technology, and microcomputer automatic data processing, the COD and ammonia nitrogen values of the sample are directly displayed. The instrument is widely used in environmental monitoring, sewage treatment, scientific research institutions, and colleges and universities.
