CHM-301 COD-Ammonia Nitrogen-Total Phosphorus Meter With CE certificate


Principle:

The instrument can be directly determine the concentration of COD, Ammonia Nitrogen and Total Phosphorus in water samples. The determination method of COD is Fast Digestion Optical Method; The determination method of Ammonia Nitrogen is Mrs. Pay Reagent; The determination method of Total Phosphorus is Phosphorus Molybdenum Blue Method. The Instrument adopts advanced cold light, narrowband interference technique and microcomputer automatic processing data, directly display the density of samples.
