  • The portable COD detector is a chemical oxygen demand testing instrument. With the application of cold light source display technology, the service life of the light source lamp is up to 100000 hours. The switch of the light path for measuring parameters changes from manual to automatic, eliminating the error factor of manual rotation. The standard method for determining COD is the reflux digestion titration method. This method takes a long time (2 hours) to digest, consumes a lot of energy, costs a lot of reagents, and has low efficiency, which often puzzles the actual operators. The instrument uses catalyst and oxidant. After adding oxidant and catalyst, the water sample is heated and digested. The Cr6+in the oxidant is partially reduced to Cr3+. The reduced Cr3+content is converted into the actual concentration of COD (cr) in the water sample through colorimetric measurement and regression calculation. The eighth generation is based on my
