Falling Ball Viscometer like Thermo HAAKE Type C
THERMO ELECTRONIC CORPORATION Type 002-7580
Serial No.:
With the Thermo falling ball viscometer, you can measure viscosity precisely without electricity, using only a stopwatch.
It allows for accurate measurement of the viscosity of transparent Newtonian liquids and gases.

Measuring principle:
A ball moves by rolling and sliding inside an inclined cylindrical tube filled with the liquid to be tested. The time it takes for the ball to travel a defined measuring distance is recorded.
By swiveling the measuring section, the return movement of the ball can also be used for measurement.
