hydrometer

It is usually a form of hydrometer with a special scale.

All of these men returned valuable observations with the hydrometer.

I have shown you how we use the hydrometer.

The Fahrenheit hydrometer can be made of either glass or metal.

Further testing, required by state law, is done with a hydrometer, which measures density.

We determined the percent silt and clay using a hydrometer.

A hydrometer can be used to measure the precise proof of a spirit.

The gravitational force acting on the hydrometer is simply its weight, mg.

Still preserved in the hydrometers, even broken ones, were delicate paper scales.

A glass hydrometer is rigid under normal pressure, for all practical purposes.

The relative density of a liquid can be measured using a hydrometer.

Thus, the lower the density of the substance, the farther the hydrometer will sink.

Constantly check the solution being heated with the hydrometer, and boil until you get a reading of 1.3.

-415), who is credited with the invention of the hydrometer.

You might have to calibrate your own hydrometer with standardised solutions.

Not to be confused with hydrometer which measures mass density of liquids.

In this classic demonstration, the floating hydrometer remains at an equilibrium position.

Hydrometers usually contain a scale inside the stem, so that the specific gravity can be read directly.

The Fahrenheit hydrometer is a device used to measure the density of a liquid.

To use the hydrometer, one first accurately determines its weight (W) while it is dry.

"Bless my hydrometer, but he's got nerve for a first trip in a submarine!

Modern hydrometers usually measure specific gravity but different scales were (and sometimes still are) used in certain industries.

Using the hydrometer, brewers could calculate the yield from different malts.

However, the hydrometer was invented before Hypatia, and already known in her time.

The Fahrenheit hydrometer is a constant-volume device that will float in water.
