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.
The result is displayed as dynamic viscosity in mPa·s.

Max. viscosity: 100,000 mPa·s
Min. viscosity: 0.5 mPa·s
Standards: DIN 53015, ISO 12058
Reproducibility: < 0.5%
Thermometer: -1 °C to +26 °C (read-out accuracy 0.1 °C)
Ball set Type 800-0182 with 6 balls (balls 1 and 2 made of borosilicate glass; balls 3, 4, 5 and 6 made of nickel-iron alloy)

Recommended for:
Chemical industry (polymer solutions, solvents, printing inks)
Pharmaceutical industry (raw materials, glycerin)
Mineral oil industry (oils, liquid hydrocarbons)
