Mooney Viscometer Mk III
- Simple and robust mechanical system producing reliable results
- Precise digital temperature control
The Mooney Viscometer Mk III measures and records the viscosity of natural, synthetic or compounded rubber.
Conforming to international standards, the Mk III is a shearing-disc viscometer in which the rubber sample is compressed pneumatically in a cylindrical chamber formed by cavities in 2 opposing dies.
The viscosity is determined by measuring the torque required to turn the rotor inside the chamber, heated to a set temperature. As the rotor shears the sample, a torque reaction is transmitted through a worm shaft, which deflects a torsion beam. A dial gauge (analogue or digital) measures the beam’s displacement.
With its simple mechanical drive system and well-proven design, the Mk III has been in use for many years and has become the benchmark viscometer for thousands of laboratories.
