<p>Apparatus for determining the vapour content of a gas/vapour mixture comprises two temperature sensing devices (4,7). One of the devices (4) measures the temperature of a liquid evaporating from a liquid saturated wick (5) in contact with the device. The other temperature sensing device (7) measures the temperature of the gas/vapour mixture in which it is immersed. A cooling device (1,14) is provided for condensing some of the vapour from the gas/vapour mixture to maintain a liquid supply for the wick (5).</p> |
