Prinsip dɔ:

COD ammoniac total phosphorus total nitrogen measurement principle, COD measurement using dissolution tube closed catalytic dissolution comparison method, ammoniac nitrogen measurement using nano reagent comparison color, total phosphorus measurement using close dissolution comparison color, total nitrogen measurement using alkaline persulfate dissolution photometry, all are U.S. EPA approved method, then imported cold light source, narrow band interference technology and microcomputers for data processing, directly show the sample COD, ammoniac nitrogen, total phosphorus and total nitrogen values, in units mg/L.
