Abstract
PURPOSE:To remove stain of a humidity-sensitive material and absorbed humidity completely by supporting a humidity-sensitive element with a humiditysensitive film formed on the surface of an insulating substrate on columns while an oval or rectangular frame-shaped heater is provided on the circumference thereof. CONSTITUTION:An insulating substrate 1 with a humidity sensitive film printed is supported vertically on columns 3 with a wire 2. A rectangular heater 6 is wound on the circumference of the columns 3 to heat the substrate 1 from outside. This allows a heat-sensitive element to be heated evenly and entirely while the columns 3 to be partially heated thereby maintaining uniform temperature distribution without escaping heat through the wire 2. This, stain of a heat sensitive material and absorbed humidity can be removed completely to secure accurate results of the measurement.
