The High Resolution Research Rheometer

STRESSTECH 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.

For precise control of sample temperature, KINEXUS offers a series of environmental control systems ranging from circulating fluid bath, through Peltier plate and couette, to a circulation airflow furnace for a wide temperature range and maximum temperature stability.



Temperature Control Units The instrument can be delivered with temperature control units using either thermostat liquid or resistively heated/adiabatically cooled furnaces for plate/plate, cone/plate, and solids testing. The VISCOANALYSER system was designed following a modular concept, and can be upgraded to meet a user's expanding needs and requirements without any compromise in performance.



Standard software allows frequency sweep testing and a special SHRP program provides binder specification testing at 10 rad/s.VISCOANALYSER DSR was specifically designed with resistively heated lower plate and radiant heated upper plate, rather than the conventional water circulating bath systems.



Also featured are Extensional Viscosity measurement by convergent flow, hyperbolic die or precision melt strength system with optional extrudate profile measurement. High precision is achieved through the use of tungsten carbide dies, multi-point calibration and high precision transducers and amplifiers. Both floor and bench top models are available with singe and dual bore capabilities.


BLACK PEARL Viscometer

Designed for performing both routine rheological tests like single point viscosity checks for QC, to complex rheological evaluation for R&D, the BLACK PEARL viscometer is ideal for investigating the mixing, stirring, and process flow characteristics of fluid systems. BLACK PEARL Viscometer is a high performance rotational viscometer capable of both steady shear and yield stress testing in a rugged.
