Dissolved Carbon Dioxide Sensor
Dissolved Carbon Dioxide Sensor is used to detect concentration of CO2 in solution. It can measure the concentration using datalogger and experiment software. The dissolved CO2 in sample diffuses in the thin liquid layer between pH electrode and gas-permeable membrane. The reaction will occur until partial pressure of sample and thin liquid layer are same. CO2+H2O H++HCO3- The change of pH of thin liquid layer is measured by combination electrode. The measured potential value and concentration of CO2 in external solution are compliance with Nernst formula.
