摘要

穀物水份計的量測性能在農產品加工作業上十分重要。此研究中，以烤箱法所得之含水率爲標準值。用以測定紅外線水份計和大發型電阻式水份計之精密性與準確性，所得數據以統計技術加以分析。實驗結果顯示紅外線水份計量測性能受到操作者技術影響。在適用範圍內準確性約0.5%。電阻式水份計有良好之精密性，每具水份計必須有其特定之校正曲線。經校正公式改良後的準確性約0.3%。此型水份計可適用於乾燥機之自動控制作業。

The performance of grain moisture content meter is an important factors on the processing operaion for agricultural products. In this study, the accuracy and precision of measurements form Infrared Ray meter and Da-Far resistant type m. c. meters were tested and analysed by statistical technique. The m. c. values obtained from the Oven method were adopted as the standard values for comparing. The precision of Infrared Ray meter were affected by the technique of operators. Its accuracy was nearly 0.5%. The resistant type m. c. meter had the good precision. Each m. c. meter had its specific calibration equation. The accuracy could maintain within 0.3% with the modification of the measurement value by the adequate calibration model. The resistant m. c. meter could serve as good sensor for the auto-control operation of grain dryers.
