B-type viscometer (spindle)

TV-100B / 200B type viscometer

The rotor is a spindle type B-type viscometer.

The feature is that the measurement range is very wide due to the multi-range function.
One unit boasts the measurement range of three conventional viscometers and has excellent cost performance.

Recommended when you want to measure samples of various viscosities with one unit.

* The TV-200B series comes standard with viscosity data acquisition software (Visco-Chart).

Touch panel

Equipped with a 4.3-inch LCD color touch panel, the screen is easy to see and operability has been improved.


Depending on the viscosity value of the sample to be measured

Low viscosity:L type
High viscosity:H type

It is divided into two models.

Low viscosity (L type)
“M”, “2.5M”, “5M”

High viscosity (H type)
“H”, “R”, “U”

It covers 3 ranges and
It has a measurement range equivalent to that of three conventional viscometers.

This makes it possible to measure multiple samples with different viscosity values.
In addition, since measurement can be performed at a wide range of rotation speeds (share rate), the range of sample evaluation is expanded.

Operating principle

The viscous torque detector is divided into a drive frame and a sensing frame, which are connected by a flex pivot.
A feedback current flows through the Torquer so that the deviation between the drive frame and the sensing frame generated during measurement becomes zero, pushing the sensing frame back.
This measurement method is a measurement method that always returns the deviation to zero (equilibrium) and is called the “zero position method”.

Due to the “pivotless mechanism” that does not use the jewel bearing used in conventional viscometers, it has excellent linearity and reproducibility even in a wide measurement range.

Program function (TV-200B only)

You can set 10 patterns of programs up to 40 steps.

Set “rotation speed”, “measurement range” and “measurement time” for each step.

Since the operation is always fixed, stable measurement with good reproducibility is possible.

Non-Newtonian samples exhibit various behaviors depending on the timing of changes in rotation speed (shear rate) and the difference in measurement time.

Therefore, when measuring such a sample, by using the program function, it is possible to measure with a constant operation regardless of who is measuring it, so stable measurement is possible.

In particular, it is an essential function when you want to obtain flow analysis and TI value (thixotropy index).

Visco-Chart (Standard accessory for TV-200B only)

This software imports viscosity data into a computer.

graph in real time

By graphing in real time, sample characteristics can be visualized and easily evaluated.

In addition, the simple analysis function can calculate the “hysteresis loop area” and “non-Newtonian viscosity index”.

Data compatibility

The TV-100B/200B viscometer conforms to JIS and ISO standards, and the measured data is compatible with other viscometers manufactured by our company.

Standard accessory spindle rotor

The B-type viscometer comes standard with the following spindle rotors depending on the range type.

  • L type : TM1 to TM4 4 pieces
  • H type : TH2 to TH7 6 pieces

Small volume sample adapter

By using the optional small volume sample adapter, viscosity measurement can be performed with small volume samples (8 to 13 ml).

  • Viscosity measurement of expensive samples
  • Viscosity measurement of a small amount of prototype sample
  • Dangerous sample viscosity measurement if handled in large quantities

* When using a small volume sample adapter, the sample volume is small, so temperature control using a constant temperature water bath is required.

Low viscosity adapter

By using the optional low-viscosity adapter (L adapter), it is possible to measure the viscosity of low-viscosity fluids that cannot be measured with the standard rotor.

Another feature is that it can be measured with a small sample volume (approximately 22 ml).

* When using a low-viscosity adapter, temperature control using a constant temperature water bath is required because the amount of sample is small.

T-bar stage

For samples that are difficult to measure with a normal B-type viscometer (paste, gel, pudding, jelly, etc.), the T-bar stage enables stable measurement.

Temperature sensor

The TV-100B / 200B has a temperature display function.
By using the optional temperature sensor “PB-100”, it is possible to measure the sample temperature inside the measuring container.

About sample temperature control

Temperature control of the sample to be measured is very important in viscosity measurement.

By using an immersion type constant temperature water bath, the temperature can be kept constant, enabling more stable viscosity measurement.


Viscosity data and temperature data can be printed by connecting an optional printer.
