The method of measuring of the density consist of determining the mass of tested material, which is placed to the container (pycnometer) of known volume at a certain temperature. To calculate the density the obtained weight divided by volume of tested liquid.
Density cup (pycnometer) NOVOTEST P-1 is complies with ISO 2811-1.
Operation principle
The tested material is poured into pycnometer, after that the cap is covered with overflow hole. Surpluses of fluid, which are flowing through overflow hole carefully removed with a soft material (if necessary, moistened with solvent).
The density of paint or other material is calculated by formula:
ρ = (m2 — m0) / V, where
m0 – mass of empty pycnometer, g
m2 – mass of pycnometer with tested material, g
V – volume of pycnometer cm3.
