Hydrometers (cont’d)

We’ve tried to provide a detailed description of how to take

hydrometer readings, and while this description is lengthy, it

will take less time to use, clean, and, dry the hydrometer and

cylinder after use that it did to read these tips and instruc-

tions.

To recap the procedure:

Pour your sample into a smooth, clear cylinder that is

dry or well rinsed with a portion of the sample

Make sure your sample is thoroughly mixed before test-

ing.

Immerse the hydrometer in the liquid to a point slightly

below the place where it naturally floats. Make sure the

hydrometer and liquid are at rest and free of air bubbles.

Measure the temperature of the sample. Ideally, the

sample temperature should be equal to the tempera-

ture standard of the hydrometer, generally 60°F. If tem-

perature differences are unavoidable, correction tables

can help to adjust readings—call our Applications

Specialists for information.

Take your reading at the point where the surface of the

liquid crosses the hydrometer and not where the menis-

cus curve climbs up the wall.
