TA Instruments Discovery HR-1 Rheometer

The Discovery HR-1 Rheometer by TA Instruments is a robust and accurate instrument, renowned for its field-proven reliability. Sharing the advanced technology of the Discovery Hybrid Rheometer family, the HR-1 is perfectly suited for applications in production control, asphalt manufacturing, and varied general measurements of viscosity and viscoelasticity. It features magnetic thrust bearings, porous carbon radial bearings, and a drag cup motor design. The HR-1 offers a minimum torque oscillation of 10 nN.m, a steady shear minimum torque of 20 nN.m, and a maximum torque of 150 nN.m, with a torque resolution of 0.1 nN.m. Its frequency range spans from 1.00E-07 Hz to 100 Hz, and angular velocity ranges from 0 to 300 rad/s. It includes an optical encoder for displacement measurement, providing a resolution of 10 nrad. Step time for strain is 15 ms, and for rate RI, 5 ms. The normal/axial force transducer (FRT) handles up to 50 N of normal force, with a sensitivity of 0.01 N and a resolution of 1 mN.
