| Outline of Final Research Achievements |
Superheated steam or high-humidity air at temperatures higher than the boiling point of water are used as heating media in food heating appliances such as steamers and ovens. In this study, we developed a humidity generator to calibrate humidity measuring devices. The uncertainty of the generated humidity was evaluated based on GUM; the results indicate that our device has satisfactory accuracy and can be used as a calibration system for humidity sensors for high humidity and high temperature air, including superheated steam.
