The ViscoCIock plus is an electronic timing unit for glass capillary viscometers used to determine kinematic and relative viscosity. Succeeding the well-proven ViscoCIock, the new instrument features data storage and simpler handling. The ViscoClock plus is especially designed for Ubbelohde type viscometers which are well-known for highest precision. The ViscoClock plus automatically measures the flow time of temperature-stabilized liquids in capillary viscometers by means of infrared light barriers: the manual measurement with a stopwatch becomes obsolete. The viscometer including a sample is inserted into the ViscoClock plus and immersed into a thermostatic bath for temperature stabilization. After thermostating, the sample is pumped into the measuring bulb, and the fl ow time is detected automatically. The large display enables easy read-off of fl ow times and additional information: date, time, sample ID and viscometer ID.
- Automatic and precise flow time measurement for a low price.
- Suitable for SI Analytics® Ubbelohde, Micro Ubbelohde and Micro Ostwald viscometers.
- Data storage incl. time, date, viscometer and sample ID.
- Stand is made of high performance engineering plastic PPA and enables measuring temperatures up to 150 °C.
- Electromagnetic venting valve for convenient handling of Ubbelohde viscometer.
- Compatible with all SI Analytics® thermostatic bath types.
|Measuring range time:||up to 999.99 s; resolution 0.01 s|
|Accuracy of time measurement:||± 0.01 s / ± 1 digit; however no more precise than 0.1 %;|
indicated as measuring uncertainty with a confi dence level of 95 %

the absolute, kinematic viscosity is additionally dependent on the uncertainty of the numerical value of the viscometer constant and on the measuring conditions, in particular
the measuring temperature.
