7-4. Measuring the Absolute Value of Viscosity Using the Small Sample Cup
The SV-10A/100A has been calibrated using the accessory sample cup (45 mL) when shipped. The
distance between the inner wall and the sensor plates when the accessory sample cup is used,
differs from the distance when the small sample cup (10 mL) is used. This causes a difference in the
sensor plate's detection capability, thus causing a difference in the viscosity measured.
Therefore, to measure the absolute value of viscosity using the small sample cup (10 mL), it is
recommended that calibration be performed using a fluid with a known viscosity value which is close to
the sample viscosity. (Refer to "8. VISCOSITY CALIBRATION" of the viscometer instruction manual.)
7-5. Maintenance
Clean the sample cup as necessary. If cleaning is not sufficient, a measurement error may occur due
to contamination.
7-6. Specifications
Operating temperature:
0°C to 100°C
Circulation nozzle outside diameter: 10.5 mm
Recommended hose:
Silicone tube with an inside diameter of 8 mm
When a stirrer is attached at the bottom of the water jacket, the sample viscosity can be
measured while the sample is being stirred. The maximum viscosity value which can be
measured is 1000 mPa

Note
•
Use a rotator with a size of 6 mm (length) x 4 mm (diameter).
•
Attach the stirrer to the bottom of the water jacket, using an M4 screw from below.
•
When the rotator is used, make sure that the rotator will not touch the temperature
sensor or the sensor plates. If it does, increase the sample amount so that the rotator will
be farther away from the sensor plates.
•
Use the stirrer with a revolution speed which will not cause ripples in the sample surface.
