Viscoball
The Viscoball measures accurately the viscosity of transparent Newtonian liquids and gases (with a special glass ball).

Features

New
Changeable angle

Fixed angle
Complies with
DIN 53015 / ISO 12058

Kit of 6 balls
Wide viscosity range covered

Simple thermostatic
Measuring with easy conection to our thermovisc series

Viscosity readings
Dinamic (cP or mPa·s)
Kinematic (cSt)

Reproducibility: 0.5%
Comparability: 1%


Viscosity range
0.5 - 10^5 mPa·s (cP)
0.5 - 105 mPa·s (cP)

- High accuracy through improved visibility of falling ball.
- Minimized test time due to accurate return run of the ball.
- Reduced cost of ownership through increased life time of falling tube.
- Extended re-calibration periods through improved bearing support.

The VISCO BALL viscometer is mainly used for low viscosity substances such as used in:
  • Mineral oil industry (oils, liquid hydrocarbons).
  • Food industry (sugar solution, honey, beer, milk, gelatine, fruit juice).
  • Chemical industry (polymer solutions, solvents, resin solutions, latex dispersions, adhesive solutions).
  • Cosmetic/Pharmaceutical industry (raw materials, glycerine, emulsions, suspensions, solutions, extracts).
  • Petroleum industry (light crude, machine oil, crude petroleum).
  • Fuels (petrol, diesel oil, paraffin).
  • Paper industry (emulsions, pigment dispersion, paper additives).
  • Paints and varnishes (printing inks, varnishes, water lacquers, inks).
  • Detergents (liquid washing agents, washing-up liquids, tenside solu- tions).

Measuring principle
The rolling and sliding movements of a ball through the sample liquid are timed in an inclined cylindrical measuring tube. The sample viscosity is correlated to the time a ball requires to traverse a definite distance. By turning the measuring tube upside down again the return of the ball may also be used for an additional measurement applying the return cons- tant. The test results are given as dynamic viscosity in the internationally standardized, absolute units of mPa·s.
