The High Resolution Research Rheometer
HR represents the latest development effort from ATS RheoSystems. Based on the STRESSTECH platform, STRESSTECH
HR represents the highest performance research grade rheometer available
in the world today. With enhanced position resolution and ultra low
torque capability, measurements never before attainable are now available.
STRESSTECH HR was designed for the researcher who requires
the very best. The instrument couples nano radian position resolution
and nano Newton meter (nNm) torque range, with our patendted Differential Pressure Quantitative Normal
Force Sensor, and Windows XP compatible RheoExploer V5
operational software. Steady shear, transient (creep/stress relaxation) and periodic (dynamic
oscillation) testing modes are available. Samples can range from low
viscosity fluids to high modulus solid materials. The instrument is
built around a dedicated, high speed bit computer for unprecedented
performance, versatility, and reliability. Remote control operation,
remote diagnostics,and service is available via the internet.
The patented Differential Pressure Quantitative Normal Force Sensor is non interactive,
and does not cross talk with the torque signal. The Normal Force Sensor
has a wide dynamic range and can be used for both user selectable
constant force loading and quantitative normal force measurements.
Neither the normal force or torque signals interferes with the motion,
or applies any external forces on the air bearing. This technology
is unequaled in the industry. The instrument has automatic, real time,
inertia compensation (not a software correction after the data is
collected), and automatic temperature compensation of the gap during
temperature sweep experiments. RheoExplorer is a true 32 bit Windows
interface designed for Windows XP with true multi-tasking capability. The user can easily transfer data to any other Windows application, can support
any Windows compatible output device, and can send data directly to
a network server. Both Time/Temperature Superposition, IRIS (licensed
from Dr. H. Winter at University of MA), and advancned rheological modeling are available. Being built around a dedicated, on board computer, the instrument hardware provides adaptive, direct control for
constant rate and constant strain measurements. All electronics are
built into the instrument to minimize bench space requirements. Output
from the instrument is through an industry standard RS232 line to
any PC with an open com port. There is no interface
card or software key limitations, and the computer
is not dedicated to just running the rheometer.
Not satisfied only with instrument performance, all instruments come with installation and commissioning, and a full 1 year parts and labor warranty. Software updates are included at
NO CHARGE during the warranty period and with PM&C coverage. Subsequent
to the warranty period, a full spectrum of extended service agreement options are available.
