The Rotothinner digital viscometer uses a disc or ball shaped rotor to determine the fluid viscosity of the sample under test. The results are displayed on the LCD screen in POISE units.

Rotothinners allow the operator to continuously monitor the samples viscosity whilst a solvent or thinner is added. This allows quick correction factors for use in the production batch when carried out quantitatively.

The fluid viscosity is measured using a high quality microprocessor controlled DC motor. The robust construction of the Rotothinners means that they are suitable for use as both production and laboratory instruments. Supplied with a 250ml sample tin.
