1. INTRODUCTION

This manual describes how the SV-A/SV-H series viscometer works and how to get the most out of it in terms of performance.

Read this manual thoroughly before using the viscometer and keep it at hand for future reference.

The SV-A series uses a stand. In a laboratory, quality control room etc, you can make accurate

measurements using the stand set, the sample cup set and the software set provided.

The SV-H series uses a handle only. While at a manufacturing location, you can make a

measurement easily. If you buy the accessories, the SV-H series functions the same as the SV-A

series.

Safety of Information Technology Equipment

1-2 Features

 High accuracy

The Vibro Viscometer adopting the sine-wave vibration technique (SV type), achieves a high

measurement accuracy of 1%*

*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.

(repeatability) over the full range.

 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.

 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. In case of a Newtonian fluid, 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-A/SV-H series viscometer can be combined into those obtained by the other type of viscometer. The vibro viscometer and the

capillary viscometer and the rotational viscometer are a type of

calibration equipment for viscosity measurement by JCSS standard (Japan Calibration Service System).

 Simplified calibration when measuring the viscosity near 1 mPa⋅s (Only for SV-1A/1H/

10A/10H) Simplified calibration using purified water is a one-key operation. The SV-1A/1H/10A/10H 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 (With the SV-A series, it is standard

accessory. With the SV-H series, it is sold separately (AX-SV-53-EX)) Windows communication tools WinCT-Viscosity (CD-ROM) is provided as standard. The CD-ROM contains the graphing program RsVisco, which imports the data into 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.

 When using the accessory serial / USB converter, the personal computer can input the data

using the personal computer’s USB port. (With the SV-A series, it is standard accessory. With the SV-H series, it is sold separately (AX-SV-53-EX))

 The cup, that the sample is to be measured in, can be the plastic sample cup and the glass

sample cup. When measuring an organic solvent, use the glass sample cup.

 Use the carrying case only for carrying the viscometer. Do not transport the viscometer using

the carrying case. Doing so may cause damage to the viscometer. When transporting the viscometer, be sure to use the original packing material.

2. UNPACKING THE VISCOMETER

 The viscometer is a precision instrument. Unpack the viscometer carefully. Keep the packing

material to be used for transporting the viscometer in the future.

5. PRECAUTIONS

To get the optimum performance from the viscometer and acquire accurate measurement data, note the following:

5-1 General Precautions (For all models)

For accurate measurement, use care with the following conditions.

 Install the viscometer in an environment where the temperature and humidity are not excessive.

The best operating temperature is 25°C±2°C at 45-60% relative humidity.

 For precise measurement, install the viscometer where there are no great changes in

temperature and humidity.

 Install the viscometer where it is free of dust.

 The viscometer uses the Tuning-fork Vibration Method. So, use much care to avoid external

vibration, especially when measuring low viscosity. Places where the viscometer is prone to vibration are: Second or higher floor, soft ground, near busy highways or rail lines. Avoid these places as a measuring site. If measurement is to be performed in such a place, use an anti-vibration table that is available as an option (AD-1685).

 Do not measure where heaters or air conditioners can affect the measurement.  Do not measure where direct sunlight can affect the measurement.  Install the viscometer away from equipment which produces magnetic fields.  Protect the internal parts from liquid spills and excessive dust.  Do not disassemble the viscometer.

 When precise measurement is required, acclimatize the viscometer to the measuring

environment. After installation, plug in the AC adapter and warm up the viscometer for one hour or more.

5-2 Precautions for an Accurate Measurment (Only for the SV-H series)

 With the SV-H series, when you need to make an accurate measurement, adjust the height of

the sample surface and sensor plates correctly by using the AX-SV-51 stand set. The specification values are when using the stand set.

5-3 During Use (For all models)

 The SV-A/SV-H series viscometer, designed for very accurate measurement, is sensitive to

vibration or shock during transportation, as that may cause a display value error. Before measurement, calibrate the viscometer using the sample cup that will be used for measurement.

 To level the surface of the sample, adjust the leveling feet. (Height adjustment of the right and left

leveling feet.)

(With SV-10A, the center of the narrow part of the right and left sensor plates is on the liquid

surface.)

* With the SV-H series, use the AX-SV-51 (stand set, sold separately).

 The viscosity of a liquid is temperature dependent and changes by negative 2 to negative 10

percent, per degree Celsius. Take changes in the liquid temperature into consideration for an accurate measurement.

 Be sure to calibrate using the standard viscosity fluid or purified water before measurement.

In a measurement that takes a long time, perform calibration periodically, as necessary.

 Ensure a stable power source when using the AC adapter.

 Placing the sensor plates and the temperature sensor in the sample may change the sample

temperature. For precise measurement, leave the sample as is for a while, after placing the sensor plates and the temperature sensor, to ensure no changes to the sample temperature. And then, start a measurement.

 Use only your finger to press the keys. Using a sharp instrument such as a pen may damage

keys.

 Handle the sensor plates with care.

 If the sensor plates, or the protector, touch the inner wall of the sample cup, it may cause

measurement error. When measuring, be sure to adjust the spacing between the sensor plates and the inner walls of the sample cup.

 The sample cups are made of polycarbonate (PC) or glass. When using organic solvents, we

recommend the use of the glass sample cup (accessory or sold separately) or a commercially available glass beaker.

Raise or remove the protector if necessary.

How to remove the protector:

Press the left and right side frames lightly in the direction indicated as 1 to remove the rotational axis. Pull the protector in the direction indicated as 2 to remove.

5-4 After Use (For all models)

 Remove any residual sample material from the sensor plates, temperature sensor and

protector using alcohol. Using the sensor plates, temperature sensor and protector with residue of an old sample left on will cause a measurement error. Clean the sensor plates carefully to avoid bending them. The sensor plates and the temperature sensor are made of titanium.

How to clean the sensor plates and temperature sensor

SV-1A/SH-1H

Hold the sensor plates with folded tissue paper.

Move the tissue paper upward and downward to

remove the sample. Pushing strongly on the

sensor plates when moving the tissue upward, may

cause the sensor plates to bend.

Clean the temperature sensor in the same way.

Then, use tissue paper moistened with alcohol,

to remove any residual sample material.

SV-10A/SV-10H/SV-100A/SV-100H

Hold the sensor plate or temperature sensor with

tissue paper. Move the tissue paper downward to

remove the sample.

Then, use tissue paper moistened with alcohol,

to remove any residual sample material.

5-5 Measuring the Absolute Value of Viscosity (For all models)

The SV-A/SV-H Series Sine-wave Vibro Viscometer, as a measuring principle, detects the product of viscosity and density.

Displayed viscosity value = Viscosity × Density ⋅ ⋅ ⋅ ⋅ ⋅ [1] While the displayed value has a unit of mPa⋅s, it indicates the product of viscosity and density.

Example (1) When a sample has an absolute value of viscosity of 2.00 mPa⋅s and density of 1.000: Displayed value = 2.00 [mPa⋅s] × 1.000

= 2.00 [mPa⋅s]

(2) When a sample has an absolute value of viscosity of 2.00 mPa⋅s and density of 0.800: Displayed value = 2.00 [mPa⋅s] × 0.800

= 1.60 [mPa⋅s]

Note

The density can be measured, using the density determination kit, AD-1653 in combination with a balance.

To obtain the absolute viscosity value precisely, do as follows:

5-5-1 At Measurement

Divide the displayed viscosity value by the sample density to obtain the absolute value of viscosity.

Example (1) Measure the sample and confirm the displayed viscosity value. Here, 736 mPa⋅s as an example.

(2) Check the sample density at the temperature when the sample is measured.

Here, 0.856

(3) Divide the displayed viscosity value by the sample density to obtain the absolute value

of viscosity. Here, 860 mPa⋅s is obtained as the absolute viscosity value.

Absolute value of viscosity =

5-5-2 At Calibration

When calibrating, enter the product of the absolute viscosity value and the density of the standard viscosity fluid used for calibration, as a correction value.

The standard viscosity fluid has the calculation sheet of kinetic viscosity and viscosity at various temperatures attached. To obtain the correction value using this sheet, do as follows:

Kinetic viscosity = From this, Density = ⋅ ⋅ ⋅ ⋅ ⋅ [2]

Correction value = Viscosity × Density ⋅ ⋅ ⋅ ⋅ ⋅ [3]

When substituting [2] for the density in [3], the following equation is obtained.

Correction value = ⋅ ⋅ ⋅ ⋅ ⋅ [4]

Example 1: To calibrate the viscometer using a standard viscosity fluid:

Using the calculation sheet, calculate the value used for calibration.

as an example.

(2) Substitute the values above into equation [4].

781 mPa⋅s is obtained as a correction value used for calibration.

(3) After calibration, measure the viscosity of the standard viscosity fluid used and confirm

that the viscometer displays the similar value as the correction value, 781 mPa⋅s in this example. This completes the calibration procedure.

Example 2: To calibrate using a standard viscosity fluid with known values of viscosity and density.

In this example, a standard viscosity fluid with a viscosity of 889 mPa⋅s at 20°C is used.

(1) Check the viscosity value and the density of the standard viscosity fluid at the

temperature when the calibration is performed..

Here, 889 mPa⋅s for the viscosity and 0.878 for the density at 20°C as an example.

(2) Substitute the values above into equation [3].

889 × 0.878 ≅ 781 781 mPa⋅s is obtained as a correction value used for calibration.

(3) After calibration, measure the viscosity of the standard viscosity fluid used and confirm

that the viscometer displays the similar value as the correction value, 781 mPa⋅s in this example. This completes the calibration procedure.
