Mooney Viscometer Mk III
- Simple mechanical system producing reliable results
- Precise digital temperature control
- 4 models to suit differing requirements & budgets Automatic operation and data recording
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.
Two versions are offered:
V3/2 All digital output including PC interface
V3/3 As V3/2 with 24 character column printer
Standard accessories
Large and small diameter rotor, set of tools
Optional Accessories
Calibration Kit, S1 Specimen Cutting Press, air compressor, calibrated butyl rubber for rapid check of viscometer
