Falling ball viscometer

Article No. 18220-00

For the precise measurement of the viscosity of transparent Newtonian liquids in combination with a circulation thermostat. The fall time of a ball with density r₁ in the test liquid with density r₂ is measured while it moves through an inclined cylindrical fall tube. From this fall time and a constant K taken from the apparatus table, the dynamic viscosity η is determined.

Measuring range0.6 … 75,000 mPa·s (cP)
Temperature range-20 … +150 °C
Accuracy0.1 °C
Fall tube diameter15.95 mm
Included in delivery6 falling balls. Thermometer -1 … +26 °C (graduation 0.1 °C). Cleaning device. Ball gauge. Ball tweezers. Case and test certificate
