- an instrument for determining the specific gravity of a liquid, commonly consisting of a graduated tube weighted to float upright in the liquid whose specific gravity is being measured.

Historical Examples of hydrometer
If this hydrometer is placed in a liquid, it will sink to a certain depth.
The rubber tubing on the hydrometer should not be withdrawn from the cell.
The first is that the readings taken with a hydrometer will then be misleading.
This is another reason why hydrometer readings should be used as a guide.
It indicates the strength and is measured by the hydrometer.
- an instrument for measuring the relative density of a liquid, usually consisting of a sealed graduated tube with a weighted bulb on one end, the relative density being indicated by the length of the unsubmerged stem
- An instrument used to determine specific gravity, especially a sealed graduated tube, weighted at one end, that sinks in a fluid to a depth indicating the fluid's specific gravity.gravimeter
- An instrument used to measure the density of a liquid as compared to that of water. Hydrometers consist of a calibrated glass tube ending in a weighted glass sphere that makes the tube stand upright when placed in a liquid. The lower the density of the liquid, the deeper the tube sinks.
