摘要
Based on practical requirements and research information, humidity calibration chamber design aims are given. The gas generator will be used for establishing the relationship and accuracy of different humidity measuring devices and how they compare against a percentage rh wet and dry hygrometer together with chilled mirror measurements to provide further links in the traceability chain. Measurements will also be taken of any pressure differences, etc. found when the measurements are taking place by use of a reference standard. 7 refs.
