ISAAC is easy to set up and operate. The small foot-print means that Isaac can be easily accommodated on top of or adjacent to a viscometer bath. Opening the ISAAC App will take the user straight to the measurement screen via a simple log in procedure. Sample details are entered into the sample testing configuration screen.


The test mode is selected along with any other parameters e.g. type of sample for ASTM D445 determinability precision.


When ready, the user presses the “Start Test” button and the measurement process will commence automatically. This includes drawing the sample up the capillary, holding and releasing for each flow time measurement. All measurement data is recorded as well as the calculation of determined viscosity results and final viscosity results.
