1-2 Features
High accuracy
The Vibro Viscometer adopting the sine-wave vibration technique (SV type), achieves a high
measurement accuracy of 1%*
1
(repeatability) over the full range.
*1 With the SV-H series, when using the AX-SV-51 stand set (sold separately).
Refer to "16. SPECIFICATIONS" on page 86.
Measurement of a small amount of sample
The SV-1A can measure with a 2 mL sample (minimum amount), and the standard X-Y-Z
stage can position the sample container easily.
When using the accessory items (sold separately), the SV-1H can measure with stability a 2
mL sample (minimum amount). For details, refer to "17. OPTIONAL ACCESSORIES"
With the SV-H series, you can measure the viscosity at the manufacturing location by using
the standard carrying case.
The sensor plates are made of corrosion resistant titanium. Although titanium is a chemically
stable material, it is corroded by some liquid such as sulfuric acid. So, handle it with much
care.
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. With
SV-1A/1H, the temperature sensor is located behind the two sensor plates. With the
SV-10A/10H/100A/100H, 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. With the SV-H series, use
the AX-SV-53 Software set-WinCT Viscosity (sold separately).
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.
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. Therefore, the
viscometer can be used for a continuously flowing product line, which enables field
management with identical data used at the laboratories.
