Expert in Water Quality Measurement and Water Treatment Project Since 2007
BOQU CODG-3000 Online COD Analyzer adopts the detection principle of potassium dichromate oxidation photometric method. The pretreated water sample is oxidized and digested by potassium dichromate under high temperature and high pressure, and then photometric detection is carried out to complete the rapid determination of COD concentration. The measurement method adopted by the COD Analyzer meets the requirements of dichromate method for the determination of chemical oxygen demand of water quality (gb11914-89) and rapid digestion spectrophotometry for the determination of chemical oxygen demand of water quality (HJ / T 399-2007).
Technical Feature of CODG-3000 Online COD Analyzer
With the patented nine way valve design, the reagent consumption is 1 / 5 of that of conventional technology, and the workload of operation and maintenance is low;
High precision liquid quantitative design, stable volume of sample / reagent, without frequent replacement of pump pipe;
The high temperature digestion method is consistent with the national standard digestion method, and the high pressure digestion method has good digestion efficiency;
Brand new reagent, simple reagent purchase process; The self prepared reagent process is simple and convenient, and the preparation time is significantly reduced
Various measurement modes such as cycle and timing can be flexibly set according to the drainage conditions, which is convenient for field application.
CODG-3000 Online COD Analyzer can be used for pollution source water quality monitoring (including municipal sewage inlet and outlet; industrial sewage outlet); Industrial process water monitoring; Surface water monitoring and other water fields.
