hydrometers

we use hydrometers to measure the specific gravity of liquids.

the lab technician calibrated the hydrometers before the experiment.

carefully read the hydrometer's scale to determine the density.

the hydrometer floated in the solution, indicating a lower density.

he purchased a new hydrometer for measuring battery electrolyte.

the wine maker used hydrometers to track fermentation progress.

ensure the hydrometer is clean before each measurement.

compare hydrometer readings with established standards for quality control.

a digital hydrometer provides a more precise reading than a traditional one.

the hydrometer's stem was broken, so it was unusable.

he stored the hydrometers in a dry place to prevent corrosion.
