How does temperature affect the measurement accuracy?

Measuring devices are usually set or calibrated at a temperature of
20°C. Liquids expand as the temperature increases, thereby changing the density to be measured. The flotation scale in our glycomat (for MEG + MPG) compensates for these effects within the normal range by its own expansion.
Glass areometers cannot expand, and only produce accurate measurements at 20°C. Corresponding value correction tables can be used for the different media to be measured. Our coldomat anti-freeze tester has an integrated thermometer and a value table for MEG. The gefo s/th acidity tester has a built-in thermometer.
