采用与液体密度计读数类似的方法，能够直接读出被测固体的密度。

With the steelyard , the value of solid density can be read out directly , like liquid density apparatus .

免维护蓄电池与传统蓄电池相比具有使用中不需添加蒸馏水、接线柱免腐蚀、自放电量少、增设液体密度计电眼等优点。

Compared with the traditional one , the maintenance-free battery has many good properties such as free of adding distilled water no corrosion of the terminal , less amount of self-discharge and additional installation of an electric eye for the densimeter .
