The density of liquids can be measured with hydrometers.
Density is the ratio of mass to volume of a substance and is expressed in g / ml or in g / cm3.
Transparent and opaque liquids must be measured with differently standardized hydrometers.
Are hydrometers for opaque liquids marked with a green color ring.

• - Reference temperature for density measurements = 20 ° C.
• - Hydrometers are set to this temperature.
• - Standard temperature measuring range from 0 ° C to + 35 ° C.

Each hydrometer is designed for a special measuring situation.
Influencing factors are:
- Temperature
- Surface tension
- Density.
