Abstract
PURPOSE:To easily perform accurate calibration by performing the calibration when the humidity values of an adjusting tank and a calibration tank which are linked with each other at the same temperature indicate the same value on different ventilated psychrometer. CONSTITUTION:Outside air is entered into the humidity adjusting tank B to produce air of proper humidity. This is discharged through the hygrometer calibrating tank A held at the same temperature with the humidity adjusting tank B. In this case, part of the air in the humidity adjusting tank B and part of the air in the humidity calibrating tank A are set out respectively and measured by the ventilated psychrometers Ha and Hb. The calibration is performed when both psychrometers indicates the same humidity. Consequently, the humidity is measured by the ventilated psychromaters which need not to be calibrated and then a hair hygrometer, a bimetal hygrometer, and an electric resistance hygrometer which needs to be calibrated are calibrated, so a variety of adjustments of humidity are made and the calibration is easily and accurately performed.
