MV one - Mooney Viscometer

The MV one Mooney Viscometer combines the latest measurement technology for the standard Mooney viscosity, Mooney scorch and stress relaxation measurement in the rubber industry.

The MV one is a fully featured instrument configured for standard viscosity, scorch and stress relaxation (logarithmic, ISO, linear, Mooney Stress-relaxation Rate) testing of rubber compounds under isothermal test conditions at constant speed of 2 rpm.

An optional continuously variable motor mode allows tests beyond a speed range of 0.1 to 10 rpm. The MV one Mooney Viscometer is equipped with low mass rotors that fulfill all relevant ASTM, DIN and ISO standards. All TA Instruments rubber testing instruments are built on ultra-rigid test frames and include precision temperature control, direct drive motors and the powerful and intuitive Scarabaeus Control and Analysis Software.
