YCNP-3L COD ammonia nitrogen total phosphorus analyzer

Instrument Overview
It conforms to the usage habits of domestic users and is a measuring instrument developed based on the domestic water quality situation and regulatory requirements. It complies with standards such as HJ/T399-2007, HJ535-2009, GB11893-89, and can meet the daily measurement requirements of the laboratory. The determination of COD adopts the closed catalytic digestion colorimetric method with a digestion tube, the determination of ammonia nitrogen adopts the Nessler's reagent colorimetric method, and the determination of total phosphorus adopts the closed digestion colorimetric method, 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.
