The ViscoCIock plus is an electronic timing unit for glass capillary viscometers used to determine kinematic and relative viscosity. Succeeding the well-proven ViscoCIock, this 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-stabilised 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 stabilisation. After thermostating, the sample is pumped into the measuring bulb and the flow 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.
