High accuracy
The Sine-wave Vibro Viscometer achieves a high measurement accuracy of 1%*
1
(repeatability) over the full range.
*1 Refer to "14. SPECIFICATIONS" on page 58.
Wide range continuous measurement
Continuous measurement over the whole measuring range is possible, without replacing the
viscosity detection sensor plates.
Standard temperature sensor
The temperature sensor to measure the sample temperature is installed as standard. The
temperature sensor is located between the two sensor plates. So, the accurate detection of
the relation between temperature and viscosity is possible.
Accurate measurement
Due to the low heat capacity of the viscosity detection unit (sensor plates and temperature
sensor), the time required for temperature equilibrium is short. Thus, the sample viscosity can
be measured accurately in a short time.
Long continuous measurement time
The sensor plates, with a low frequency of 30 Hz and an amplitude of less than 1 mm, apply
very little load to the sample. So, the viscometer can continuously obtain stable viscosity
values without causing a temperature rise or damaging the sample.
Measurement of a non-Newtonian fluid/foaming sample
The thin sensor plates allow little deformation of the sample texture. Thus, non-Newtonian fluid
can be measured in a stable way. And, foaming samples can be measured without breaking
minute foam particles and with less influence scattering large foam particles.
When measuring tap water, bubbles may accumulate on the sensor plates, increasing the
viscosity.
Measurement of a flowing sample
The two sensor plates oscillate in the opposite direction. So, even when a sample is in motion,
errors are eliminated. This allows measurement of a sample while being stirred. The
viscometer can be used for a flowing product line, which enables field management with
identical data used at the laboratories.
Calibration
The viscometer can be calibrated using a standard viscosity fluid or a sample of a known
viscosity. Calibration allows the viscometer to maintain the accuracy constantly.
By calibrating an actual sample, using the viscosity value obtained by another type of
viscometer as a correction value, the measurement data obtained by the SV series viscometer
can be combined into those obtained by the other type of viscometer.
Simplified calibration when measuring the viscosity near 1 mPa
⋅
s, (SV-10 only)
Simplified calibration using purified water is a one-key operation. The SV-10 has a built-in
function to measure the temperature of the purified water using the temperature sensor and
calculates the viscosity value of the purified water at that temperature.
At this time, be careful not to influence the viscosity value by generating bubbles.
Standard windows communication tools WinCT-Viscosity
Windows communication tools WinCT-Viscosity (CD-ROM) is provided as standard. The
CD-ROM contains the graphing program RsVisco, which imports the data to a personal
computer and displays the results as a graph in real time. With RsVisco, changes in viscosity
over time and temperature dependency of viscosity can be observed easily and the obtained
data can be saved in files.
