The RH7 and RH10 rheometers retain many rugged "H" frame design principles, which is the core of the instrument's ability to operate under high load conditions. The new digital drive system gives the RH7 and RH10 unmatched rheological properties in terms of speed control, accuracy and dynamic working range. The latest 32-bit Windows™-based software Flowmaster™ supports this new rheometer hardware and has many new experimental possibilities.
