For milk and other low viscosity liquid samples with a viscosity slightly higher than water, measuring the shear rate dependency is possible in the range of shear rates about 10 to 100 s-1 (the range between a unit and 10 times that unit). A feature of EMS viscometers is that they measure samples with low shear, applying as little force as possible. The shear rate range that can be measured is determined by the sample. Further, only a narrow shear rate range can be measured (the range between a unit and 10 times that unit), so the measurements are limited to within a narrow shear range, but evaluating the shear rate dependency is possible. With the EMS viscometer (EMS-1000), changing the motor rotation rate changes the shear rate. Accordingly, it is possible to evaluate shear rate dependency by changing the motor rotation rate. However, the shear rate changes depending on the sample characteristics, so it is not possible to directly control the shear rate.
