The invention aims to disclose a metering device, which can smoothly carry out the metering operation of two mixed objects. Therefore, it is easy to intuitively understand the content of the ongoing blending operation, and can easily carry out the micro adjustment of the blending amount.The metering device disclosed by the invention,It is characterized by: mixing ratio storage device,A complex mixing ratio for storing the softness of dental materials after corresponding mixing；The first metering device；The second metering device；Mixing ratio extraction device,A mixing ratio corresponding to the information related to the softness of the dental material after mixing as desired by the user；Target difference calculation device,It is used to calculate "based on the measurement results of the first measuring device,And the difference between the target value of the substance measured in the second measuring device and the measurement result based on the second measuring device calculated by a mixing ratio,I.e. target difference；And operation status notification device,Based on the differences in objectives,Report the status of measurement operation.本發明旨在揭露一種計量裝置，由於其可以流暢地進行兩個混合對象物之計量作業，因此，易於直覺理解進行中的調合作業之內容，又，可以容易地進行調合量之微調整。 本發明所揭露之計量裝置，其特徵為包含：混合比儲存裝置，用以儲存因應混合後的牙科用材料之柔軟度的複數混合比；第一計量裝置；第二計量裝置；混合比取出裝置，用以取出對應於與使用者所希望之混合後的牙科用材料之柔軟度相關的資訊之一個混合比；目標差異計算裝置，用以計算「基於依據第一計量裝置之計量結果、及一個混合比而計算之於第二計量裝置中計量的物質之目標値」與「依據第二計量裝置之計量結果」的差值，亦即目標差異；以及作業狀態通報裝置，基於目標差異，通報與計量作業相關之進行狀況。
