Abstract

Apparatus comprises two oxygen measuring cells based on the polarographic principle in a compensation circuit. The reference cell and measuring cell voltage variations resulting from temp. variations are counter connected by the reference cell and measuring cell. Each of these is connected to an intensifier with inverse feedback, and the inverse feedback of the measuring cell intensifier makes them dependent on the inverse feedback of the reference cell intensifier and the intensifiers' output voltage to be compared.
