Abstract
Using wet and dry thermojunctions instead of wet and dry thermometers for measuring relative humidity is a rather obvious variation in experimental procedure. A. V. Hill (4) used thermopiles of fifty junctions for this kind of measurement but his sensitive elements were slow in response because of large thermal capacity and large thermal conduction between junctions. Lanning (2) and later Woodrow (3) successfully used single copper-constantan thermocouples for measuring relative humidity in restricted space. Bal des (1) and McCracken (7) have used thermocouples for measuring osmotic pressure by wetting one junction with the solution to be tested and placing the couple in a chamber where the aqueous vapor pressure was at equilibrium with a solution of known osmotic pressure.
