SX-O2-1300Smooth industrial dissolved oxygen analyzerworking principle

The instrument is measured by polar spectrum method. The electrode consists of three parts, oneNTCThermistor,A positive electrode(由AGCLmanufacture), Another vaginal electrode(由PTmanufacture)Essence Yin and yang poles are immersed in an electrolyte, and the electrolyte is closed around the electrode with a gas penetration membrane with silicone rubber. When the electrode is immersed in the sample solution, the oxygen spreads through the airb time There is a fixed voltage(0.675V), Oxygen consumes cathode. This diffusion continuously proceeds until the oxygen pressure of both sides of the membrane is equal to the dynamic balance. At this time, there is a relatively balanced and stable current between the yin and theode. The current is similar to that of the content of dissolved oxygen. When you read this current, you can calculate the oxygen concentration or oxygen content at the temperature. Convert it again25Oxygen concentration or oxygen content at ° C. The chemical reactions of yin and anode are as follows:

                         cathode:O2＋4H2O＋4E-→4oh-

anode:4AG+4CL-→4AGCL＋4E-
