Several options complete the broad
application range of the CMR series
of Online Rheometers.
Different capillaries allow the user
to measure Melt Flow Index or
apparent viscosity.

Depending on the installation requirements
the rheometer as well as
the RCU is available as general
purpose version or for hazardous
locations.
Different gear pumps give the
possibility to adjust to the needed polymer
flow.
The RCU control cabinet is available
as wall mounted version or with free
standing console (option).
