Reagecon密度標準液-精選系列 特點

密度計是可以用來直接測量液體的密度的，而不需要公式ρ=m/v。密度計無論放在那種液體中都是漂浮的，這是一種平衡狀態，因此它的重力始終等于它受到的浮力。 它放入不同的液體里，浸入液體的體積是不一樣的，但是它受到的浮力都是一樣的，都等于它的重力。可以根據密度計上的刻度來直接讀出所放入的液體的密度：把它放在密度比較大的液體里，那它浸入液體的體積就小點，把它放在密度比較小的液體里，那它浸入液體的體積就大點。這樣的話密度計的刻度從下往上的示數是越來越小的，這個和量筒正好相反。
密度計的測量范圍是0—3，液體密度計在物理實驗中使用的液體密度計，是一種測量液體密度的儀器。
產液范圍如下：
0.6960-3.1140g/ml @15℃
0.6619-3.1096 g/ml @20℃
0.6878-3.1043 g/ml @25℃
0.6752-3.0852 g/ml @40℃
0.6668-3.0721 g/ml @50℃
0.6582-1.0478 g/ml @60℃
0.6407-1.0302 g/ml @80℃
產液優點：
任何配方中不采用有毒重金屬；
可與任何液牌或類型的密度測量儀器一起使用；
