The MV one Mooney Viscometer incorporates the latest measurement technology for the traditional 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 (linear, logarithmic, ISO, 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 over a speed range of 0.1 to 10 rpm. The MV one Mooney Viscometer is equipped with low mass rotors that meet all relevant ASTM, ISO, and DIN standards. All TA Instruments rubber testing instruments are constructed on ultra-rigid test frames and include direct drive motors, precision temperature control and the powerful and intuitive Scarabaeus Control and Analysis Software.
