Molecular formula : MW : CAS :
nature : gas sensing electrode placed permeable membrane and ion-selective electrode (directives electrode), the sensitive membrane between the solution. When containing gaseous solution of the analytes with permeable membrane contact, through the unknown gas permeable membrane and membrane on both sides of internal and external gas pressure quickly achieve balance through the gas permeable membrane and electrolyte solution reaction, it's a measurable value changes, with ion-selective electrode and the reference electrode composed of battery the electromotive force reflected. As measured CO2, electrolyte solution can be used within .01 Mount / liter NaHCO3 solution, pH glass electrode directed electrode measured reaction caused by the changes in pH, can be obtained COk UB>2 content.
