<p>The method and apparatus are intended for monitoring the concentration of a gas in a fluid medium, such as in a liquid or gas medium. In a probe for measuring the temperature and gas concentration in the fluid medium, a gas concentration sensor comprising first and second electrodes is supported at a probe end of a tubular support. The probe end, in use, contacts the fluid medium. A thermocouple comprising a thermocouple junction and two thermocouple wires extends within the tubular support and the first electrode of the gas concentration sensor is electrically connected to the thermocouple. In the method for monitoring gas concentration, the gas concentration is measured by monitoring a voltage between at least one of the thermocouple wires and the second electrode.</p> |
