Pycnometers are used to establish the density of coating materials, other fluids and paste products.
The density of a substance is the ratio of its mass to its volume. Unless specified otherwise, the density of the coating material is given at 20°C. The density is given by measuring the weight of a full pycnometer and deducting the weight of the empty one. The weight difference and volume are used to calculate the density.
Pycnometers consist of a container and lid with an overflow hole. There are two versions available; one made of anodised aluminium and the other of stainless steel. These Pycnometers are available in 100ccm and 50ccm versions.
All models are supplied with a manufacturer's certificate M in accordance with DIN 55 350-18. The volumes are determined by using distilled water as a test medium with tolerance 0.2%. By extra charge models are available with a tolerance of 0.05%.
