The RH7-D and RH10-D rheometry units retain much of the robust ‘H’ frame design principle, which lies at the heart of the instruments’ ability to operate under high loading conditions. A new digital drive system, gives the RH7-D and the RH10-D unsurpassed rheometry performance in terms of speed control, accuracy, and dynamic operating range. This new rheometry hardware is supported by the latest generation of 32 bit Windows™ based software, Flowmaster™, with many new experimental possibilities.
