GECO Precision Hydrometers – absolutely necessary for Exact Measurements.

GECO precision hydrometers are measuring instruments being indispensable in scientific laboratories as well as for various controls in industry. They are used to measure the densities of liquids, solutions and liquid mixtures of diverse components.

The density of a liquid is that number which indicates the weight. of one milliliter of this liquid in grams. It is preferably written down in g/ml or g/cm3.

GECO precision hydrometers consist of a cylindrical hollow body of glass having the ballast on its bottom and taking the form of a narrow cylinder at its top being called the ‘stem’. The stem holds the measuring scale.

If a hydrometer is dipped into a liquid, it immerses until its pressure balances the ascending force. The density value or the special degrees may directly be read from the scale at the hight of the liquid level.

GECO Precision Hydrometers – solve also Your Special Measuring Problems.

You may also have GECO precision hydrometers with integrated thermometer either in the floating body or in the stem above the measuring scale, depending on the special application purpose.

In addition, further special instruments can be produced on demand for various applications.
