PC Software Improves Testing Ef ciency Rubber Viscoelasticity Evaluation from Mooney Viscosity to

Stress Relaxation

The SMV-301/301RT models make it possible to set test conditions, display data in real time, and
acquire, save, analyze, or statistically process data using computer software. Furthermore, up to
four SMV-301/SMV-301RT Mooney viscometers can be controlled from one PC for more ef cient Operating Principle and Mooney Viscosity

heated to a given constant temperature. The torque on the rotor, applied by sample resistance, is
detected by a load cell and measured as the sample's Mooney viscosity.

When the viscometer connects to the software, it waits in standby mode using the previous test
conditions settings, which means tests can be performed consecutively without having to change
test conditions.
Saved test results and data can be displayed or control charts created from the data, such as graphs
or histograms.
