Abstract
A dew point temperature measuring apparatus is positioned in a sample flow channel that withdraws a sample of a gaseous atmosphere within an enclosure for measuring the dew point temperature of the gaseous atmosphere from which its humidity may be determined. The dimensions of the sample flow channel and the velocity of the gas flow past the dew point temperature measuring apparatus is controlled to assure that the flow is laminar in order to avoid unwanted heat transfer between the sample gas and the dew point temperature measuring apparatus. The dew point temperature measuring apparatus includes a pair of sensors positioned side-by-side in a top wall of the sample flow channel.
