BLACK PEARL Viscometer is a high performance rotational viscometer capable of both steady shear and yield stress testing in a rugged, compact size footprint. 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.

The unit comes standard with build in Peltier Temperature Control for all measuring systems. Cone and plate, parallel plate and concentric cylinder measuring systems are included. The measuring systems employ novel “quick capture” mounting technology. The gapping mechanism is highly accurate and user adjustable.

BLACK PEARL is interfaced and controlled with powerful Windows based software.

Key features include:

  • Real time display of test values
  • Automated program control using “Test Definition” windows to rapidly create multiple step experiments
  • Provides instantaneous viscosity flow curves
  • Interactive graphing allows full control over displayed, printed, and plotted variables
  • User enterable data sets and data comparison
  • Simple data exportation through Windows Clipboard
  • On-line, intuitive Help System

ATS RheoSystems - Products Overview

The New Star of Rheometers, More Rheology, Less Effort, The Rheometer For All Economies, The Research Grade Asphalt Dynamic Shear Rheometer, The High Resolution Research Rheometer, Floor Standing and Bench Top. Instruments for Routine Measurements and Quality Control. Instruments for Research and Development.



Also featured are patented Differential Pressure Normal Force Sensor, a Camera Viewer, Ethernet Communication, High-Speed USB port and RheoExplorer V6 software. This null balance system allows for Nano-Torque and Nano-Strain measurement control and analysis. NOVA Rheometer features a unique "Net- Zero" bias bearing system. Nano-Strain Rheological Measurement Control and Analysis. NOVA The New Star of Rheometers.



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.



The instrument couples nano radian position resolution and nano Newton meter torque range, with our patendted Differential Pressure Quantitative Normal Force Sensor, and Windows XP compatible RheoExploer V5 operational software. 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.



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.
