- The Digital Krebs Viscometer is used for measuring the viscosity of Newtonian and non-Newtonian fluids. The viscosity of a non- Newtonian material varies depending on the rate of shear, but the Krebs viscometer measures the viscosity at a set speed shear rate which provides a consistent standard. The dimensions of the paddle conform to the precise specification of ASTM D562.
- The Rotothinner is a robustly constructed instrument, which is easy to use, clean and maintain. Three models are available: a disc shaped rotor (Ref 455N/15) allows for the addition of thinners so that test samples can be adjusted to their correct viscosity and for the rapid adjustment of production batches; two ball shaped rotors (Ref 455N/65 & 455N/340) may be used for more viscous samples and for the addition of thinners more slowly.
- The principle of measurement is simple, but reliable, based on the wellestablished method of measuring the resistance of a spindle rotating in the sample under test. The resultant torque measurement, rotational speed and spindle properties are then combined to automatically calculate the resultant viscosity value.
