PZ-D-5液體比重天平說明書(English)

1.Main applications and function mechanism

Liquid specific gravity balance is used for chemical sector or

scientific research labs to measure liquid specific gravity. It has

a standard 5cm3 plumb bob immersed in liquid to gain buoyant force

that makes the beam of the balance imbalanced. In the groove of the

beam there are quantitative weights to use to make the beam

re-balanced thus obtaining correct liquid specific gravity reading

quickly.
