Chemical Oxygen Demand Test
1.Chemical Oxygen Demand Test Brief introduction
Multi-parameter water quality detection meter is a water detection meter which is promoted by Hangzhou Lohand in 2017.Rapid digestion spectrophotometry,Nexler’s reagent spectrophotometry and molybdic acid spectrophotometry were used to test the concentrations of COD,ammonia nitrogen,total phosphorus in the water.
The reacting is used by digestion tube.The digestion and color comparison are combined in one.
