| Abstract: | The structure of the membrane electrode for the dissolved oxygen meter has been studied and improved to obtain more rapid response and suppress the residual current. The concentration of electrolytic solution,pH value and leakage protection were studied in detail.The electrode was stabilized and its life time was prolonged by using the electrolytic solution containing 0.5mol 1~(-1) KCl,borax buffer and 20% of 1,2- propanediol. Double-compensation of temperature was carried out through computer program calculation with satisfactory results. |
