Selecting the Right Viscometer




According to JIS Z 8803 "Fluid Viscosity - Measurement Methods", viscometers are classified into 5 types.
1. Capillary tube viscometers*
2. Falling ball viscometers*
3. Coaxial cylinder rotational viscometers
4. Single cylinder rotational viscometers
5. Cone-plate rotational viscometers
* Viscometers 1 and 2 are used for measurement of Newtonian substances and are not suitable for non-Newtonian substances. TOKI SANGYO manufactures and markets single cylinder and cone-plate rotational viscometers.
A Single cylinder type rotational viscometers (spindle type)
[Features]:
1. 500mL measurement beaker standard.
2. Two types of standard rotors M1 ~ M4 rotors for low-to-medium viscosities and H1~H7 rotors for medium-to-high viscosities.
3. Applicable JIS standard: JIS K7117-1.
4. TOKI SANGYO Product Lineup
B type (conventional, analog type), six models - TVB-10, TVB-22, TVB-33, RB-80, RB-115 Series.
Our simple, easy-to-use type TVC-4 Series is also included in this category.
The TVB-22 and TVB-33 Series employ the multi-range method which enables measurement over a wide range of viscosities with a single unit. The RB-115 Series is intended for research and development applications.
B Cone-plate rotational viscometer (cone-plate type)
[Features]:
1. This type of viscometer is most suitable for measurement of non-Newtonian
substances where the shear rate in the sample is uniform and theoretical analysis possible. Small sample volume is less than 1ml and temperature is easy to control.
2. Standard 1°34' X R24 cone rotor. Many types of cone-rotor options are also available to match the shear rate and viscosity range enabling a wide range of viscosity measurement from kerosene to sol-gels pastes.
3. Applicable JIS standard: JIS K7117-2
4. TOKI SANGYO Product Lineup
Our RE-80, TVE-22, TVE-33, RE-115, and RE-550 Series are successors to our popular Model E viscometers.
The TVE-22 and TVE-33 Series are multi-range type viscometers which provide measurement over a wide viscosity range with a single unit. The RE-115 and RE-550 Series are ideal for research and development purposes. The RE-550 employs a spring relaxation system which allows evaluation of viscosity behavior at very low shear rates.
C Other viscometers
Viscometers for process controls are also available such as those which employ the falling cylinder method (Model F viscometers, Model I visco-sensors) as well as various types of rheometers.
