An apparatus and a method is provided for determining the equilibrium of the partial pressures of two gases having different thermal conductivities. The apparatus includes a single sensor adapter to be contacted by the two gases, and heated by a flow of electrical current through the sensor. A circuit is provided for maintaining the sensor at a constant level of electrical resistance and hence at a constant temperature. The sensor, in addition, is connected as one leg of a bridge circuit, the output of which represents changes occurring in the thermal conductivity of a mixture of the gases.
