ViscoClock plus

ViscoClock plus

Electronic timing unit for glass capillary viscometers.
Timing unit for capillary viscometer. Including power supply 100-230V and hand pump VZ 6550.
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 flow time is detected automatically. The large display enables easy read-off of flow times and additional information: date, time, sample ID and viscometer ID
