Abstract

An electrochemical gaseous measurement cell includes a housing with an anode and a cathode arranged in spaced locations in an acid electrolyte for galvanic measurement of gases which comprises an aqueous solution of an organic acid containing a polyfunctional groups suitable to yield protons during the measurement. The container, or housing, also has a membrane at an opening thereof which is permeable to oxygen.
