Measuring the specific gravity of liquids
See the simple instructions below.
Here's how to Read a Hydrometer
 |
-
Pour your sample into a smooth, clear cylinder or jar that is dry or well rinsed with a portion of the sample.
-
Make sure your sample is thoroughly mixed before testing.
-
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 temperature standard of the hydrometer, generally 60°F. If temperature 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.
