在温湿度检定箱的湿度均匀度与波动度测试中，针对现有湿度传感器准确度难以满足要求的情况，提出将同种型号规格的湿度传感器在同一台湿度标准装置上进行校准、并加修正值使用的测量方法，减小了测量不确定度，满足湿度均匀度和波动度的测量要求。精密露点仪测量结果验证了该方法的有效性。
在溫濕度檢定箱的濕度均勻度與波動度測試中，針對現有濕度傳感器準確度難以滿足要求的情況，提齣將同種型號規格的濕度傳感器在同一檯濕度標準裝置上進行校準、併加脩正值使用的測量方法，減小瞭測量不確定度，滿足濕度均勻度和波動度的測量要求。精密露點儀測量結果驗證瞭該方法的有效性。

Against the situation that the accuracy of existing humidity sensor is hard to meet the requirements of the humidity uniformity and fluctuation measurement of temperature and humidity verification chamber, a method was posed on which same type of humidity sensors were calibrated by the same humidity standard device and used by correction to diminish uncertainty of measurement and meet the measurement requirement of humidity uniformity and fluctuation. The results of dew-point hygrometer verify the effectiveness of this approach.
