    （*用于精确测量）

     

    *步.请将干净的量杯容器放置在电子秤上，并且测量数值为0.00

    第二步.请将1.00g左右样品倒入量杯容器，根据需要的倍率用蒸馏水水进行稀释，然后使用塑料吸管做进行搅均匀

    根据不同量杯的刻度不同，稀释的倍率也会不同。

    第三步.将蒸馏水倒入在量杯容器中，将样品稀释直到50.00g

    第四步.使用样品勺或者塑料吸管进行搅拌均匀，然后用移液枪或者塑料吸管滴入0.6ml在测量棱镜中

    第五步. 按下START键，Acid酸度测量值将显示出来。(如果你*次测量糖度值可以简单地按下START按钮,再次测量酸度值)
