VISCO™'s 3 "ONE's"


VISCO is very easy to set-up. The spindle can be attached with just "one touch" — simply insert the spindle in the instrument.Absolutely no complicated set-up required.


Measurement preparation can easily be done with just one hand. Place the beaker underneath the pre-set area and place the instrument on the stand. No troublesome height adjustment necessary.


Operation requires only one dial button.All operations can be performed with the simple act of "sliding" or "pushing" the dial button. No more accidental operations due to pushing the wrong button.

【VISCO™ Temp Controller】~Six Points~

The temperature controller is a lightweight, compact and constant temperature device that does not require water circulation.

Because the viscosity is greatly affected by the temperature of the sample, it is very important to control the temperature of the sample when measuring viscosity. In general, a constant temperature water bath takes time to adjust the temperature because it circulates water. In addition, it requires a large space. It also requires preparation and maintenance such as preparing water and drying water properly after use. The VISCO Temp Controller is a lightweight and compact constant temperature device that has been developed to save the time and effort brought about by conventional constant temperature water bath.

No water required

No water required

Since the peltier is used to control the temperature, the sample can be constantly warmed without the use of water. The heavy labor is no longer necessary,no longer a need to worry about algae and mold.

Reduced Time Spent

Reduced Time Spent

Because the container where the sample is placed is made of aluminum, the heat from the peltier is transferred to the sample much more efficiently requiring a shorter time.

Lightweight and Compact

Lightweight and Compact

The total weight is about 4 kg and temperature control unit only is merely 2.7 kg. Less than half the weight of a typical constant temperature water bath. The size is just about the size of VISCO™ fitting perfect, without worrying about workspace.

Function and Design

How to use

Calibration compares the true value and the value measured from the instrument. Calibration is an important task to ensure the reliability of the measurement results. Calibration is recommended when the measurement environment has changed drastically or when the measurement results are out of the norm. If you are considering routine calibration, we recommend that you decide the frequency based on the circumstance in which the instrument is used and past measurement results. ATAGO's viscometer VISCO™ provides the following standard solutions:
The standard solutions are available in various viscosity. It is recommended to calibrate with a standard solution that is close to the viscosity of samples being measured.

What is a Viscometer?

Viscosity Types There are different types viscometers that uses various measurement methods.
For example, in the Japanese Industrial Standard JIS Z 8803, viscometers are classified as follow:
• Capillary viscometers        • Falling ball viscometers
• Rotational viscometers     • Vibrational viscometers
There are also other measurement methods such as viscosity cups and Line Spread Tests (LST).
ATAGO's viscosity meter VISCO™ is measured on a principle called rotational viscosity.

Principle of Rotational Viscometer

Principle of Rotational Viscometer Rotational viscometer is one of the most common viscometers used. The structure is simple, easy to use, and the measurement range is wide and can be measured with high accuracy. When a cylindrical spindle is placed in the sample and rotated at a constant speed, the viscosity is determined by measuring the torque (shear stress) acting on the cylindrical surface. There are different types of spindles: coaxial double cylinder, single cylindrical, and cone and plate. The cone plate type can determine the flow characteristics of non-Newtonian fluids by changing the rotational speed.

QI'm considering purchasing, can I try it before I buy it?

AFree trial is available.

QHow do I choose right spindle and speed?

AStandard VISCO™ comes with three types of spindles. Please contact our sales department for the selection criteria. Guidelines for each type of beaker size, speed, and spindle are also available in the instruction manual. Note that the torque should be between 10 and 100% because load less than 10% will not have enough load on the spring.

QWhen the speed or the beaker size is changed, a different viscosity is measured. Is it measuring correctly?

AWhen the rotational speed and the beaker size change, the viscosity also changes. This is because viscosity is affected by measurement conditions. When measuring a sample, make the measurement conditions consistent.

QCan VISCO™ be calibrated?

AVISCO™ can be calibrated using a standard solution. For the value of the standard solution, please refer to the measured value in the instruction manual.

QIs there a correlation with the B-type viscometer?

ASome samples do and others don't have correlation. Check to see the correlation with the free trial unit. If there is correlation, you can use the user scale feature to set the same value to be displayed.

QCan I adjust the temperature?

ATemp controller can be used. When using a waterbath, be careful not let the water in the sample. Also, if you are measuring a high temperature sample, set the wait time and create a temperature compensation table for the measurement sample. For more information, please contact our sales department.

QIs it possible to output data?

AData can be output using the AUSB-Mini-B cable.
