ViscoClock plus

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.
Technical Data:
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 %
Measuring range - viscosity:0.35 to10,000 mm² / s (cSt)
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.
