Measuring the Mooney Viscosity and Full Compliance to Global Standards

Scorch Time of Raw or Unvulcanized Rubber The SMV-301 / 301RT allows the user to measure the Mooney viscosity, scorch time, minimum Mooney viscosity, and other characteristics of rubber

in accordance with JIS, ISO, and ASTM test methods. With outstanding temperature recovery characteristics and easy operability, it can also be used
for stress relaxation measurements or for tests that involve varying the rotor speed.

SMV-301/SMV-301RT Mooney viscometers feature a color LCD touch panel display that allows the instrument to be
operated by anyone and enhances safety.
In addition to plotting Mooney viscosity curves, the SMV-301/301RT systems include extensive functionality for
statistical analysis. Max. 200 M Capacity (or optional 400 M capacity)
The automatic calibration unit (optional) allows weights to be automatically
calibrated to ensure high testing reliability.

A V-groove die compliant with JIS, ISO, and ASTM standards ensures tests can
be performed in accordance with global standards. V-Groove Die
Torque can be calibrated easily via the touch panel by calibrating weights
using the automatic weight calibration unit (optional). The ability to perform
routine sensitivity calibration electronically via the touch panel ensures highly
reliable routine testing.

Also supports stress relaxation testing, cycle testing,

and variable rotor speed testing.

The SMV-301RT can also measure stress relaxation and decay in accordance with ISO 289-4 and ASTM D 1646. In addition, the difference in viscosity
between samples can be determined more easily by using multiple rotor speeds (between 0.1 and 20 rpm) during testing to evaluate mixing or by varying
the strain level. Performing various tests in that manner allows viscoelasticity of rubber samples to be evaluated.
