Bubble Viscometers

Bubble Viscometers

Bubble Viscometers are precision glass tubes partially filled with oils of standard viscosity. The material to be measured is placed in a matching tube and the rise time of the air bubble after inversion is compared with that of the standard tubes. This gives a simple comparative assessment of viscosity. Please note that bubble viscometers are outside the scope of our UKAS accreditation.
