Natural, Easy Test Flow

The software, which is configured to match the operation flow, offers a smooth progression through setting of conditions, starting and stopping Higher Level Evaluation Using a Variety of Analysis Methods
the test, data acquisition, data storage, and reanalysis of stored data.
Along with enhanced analysis functions, many graph generation and overlay functions as well as a zoom feature are included. Bagley viscosity correction
and calculation of shear sensitivity (shear stress/shear rate) allows estimation of molecular weight distribution.
Setting Up Test Conditions to Storing Data - All on a Single Window

All operations associated with selecting the test method (either constant temperature or constant heating rate method), setting of test conditions, and output Reanalysis of Test Data
from test start to test results can be accomplished effortlessly. Data is automatically saved, and can be re-analyzed at any time after the test using off-line
After setting a calculation interval based on the stroke or time (temperature), the
software.
viscosity/shear rate can be determined for that interval. The graph can accommodate
up to ten overlaid files, and the pointer can be used to zoom in on any designated
region of the graph.

From entering analysis conditions to displaying results, user operations can be conducted smoothly on a single window. The status of the instrument is
displayed at the top of the window to permit verification of the test status at all times. In addition, the buttons used for conducting operations are Constant Heating Rate Recalculation
arranged as easily recognizable icons, making this window easily understandable, even to first-time users. Lastly, saving and retrieving condition Method
settings is possible, which facilitates smooth routine inspections.

Advanced Analysis Using Viscosity Correction
Shear stress, shear rate and viscosity measured by a capillary rheometer are
calculated by ignoring the pressure loss that occurs at the exit and entrance of
the die. With the CFT, it is possible to obtain more accurate data using the Bagley
viscosity correction plot (a tube length correction method which assumes that the
die length has been extended for pressure correction).
