Abstract
An oxygen meter for measuring the oxygen concentration in a measured gas, having a probe type detecting section carrying at its end a solid electrolyte unit constituting a partition wall, so as to produce a signal corresponding to the difference in the oxygen concentration between the inner side and the outer side of the partition wall. The oxygen meter is adapted to be exposed to the flow of the gas to be measured or into a furnace through a hole formed in the furnace wall, thereby to continuously produce a signal representing the oxygen concentration in the gas to be measured.
