6 Determining density of liquids
At the density determination of liquids, a sinker is used whose density is known. The
sinker is weighed first in air and then in the liquid whose density is to be determined.
From the weight difference results the buoyancy from where the software calculates
the density.
Determine the steel sinker volume as described below
Or
Have it determined quickly and not expensively in our calibration DKD laboratory.

6.1 Determination of the sinker volume
Prepare the balance as described in chapter 4.3.2
determination kit".
Fill in the container with distilled water. It should be filled to ca. 3/4
th
of its
capacity. Adjust temperature until it is stable.
Prepare the sinker.
Read the temperature on the thermometer.
1. Enter the weighing mode and reset whenever required.
2. Place the sinker on the upper sample pan. Wait until the stabilisation indicator is
displayed, take down the displayed weight.
3. Place the sinker on the lower sample pan. Wait until the stabilisation indicator is
displayed, take down the displayed weight.
