Abstract
An electrochemical gas sensor assembly comprises an electrochemical gas sensor for sensing a selected gas. A filter is provided through which gas to be sensed must pass before reaching the sensor, the filter being adapted to prevent at least one non-selected gas from reaching the sensor but permitting passage of the selected gas. A temperature control system controls the temperature of the filter.
