AUTOMATIC VISCOSITY MEASUREMENT
EASY AND PRECISE
ViscoCIock plus - Measurement plus data storage
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 ViscoCIock plus
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.
Automatic measurement of flow times
The ViscoCIock plus is designed for SI Analytics® Ubbelohde, Micro Ubbelohde and Micro Ostwald
viscometers. The flow time is measured automatically by two infrared light barriers which detect the
passing liquid meniscus. The repeatability of the automatic time measurement is considerably higher in
comparison to the measurement using a stop watch. Therefore some viscometry standards allow a flow
time reduction in case of automatic flow time measurement.
Properties and materials
The ViscoCIock plus can be used for measuring temperatures ranging from -40 °C to 150 °C. The stand of
the ViscoClock plus ist made of high quality polymer PPA. For temperature stabilization in a thermostatic
bath, the following liquids are suitable: Water, alcohol, glycol, paraffin oil, and silicon oil.
The electronic measuring unit is built-in to a PP casing.
Easy handling
The ventilation of Ubbelohde viscometers is managed by an electromechanic valve which makes handling
easier in comparison to the mechanical mechanism of the previous ViscoClock.
Data storage
The measuring results of the ViscoClock plus can be stored on a USB flash drive including date, time and
sample/viscometer ID. The data are stored as pdf (non-editable) and csv (editable). Alternatively, for data
transfer the ViscoClock plus can be connected to a printer (TZ 3863) or a PC.

ViscoCIock plus - The plus for your measurements
ViscoCIock plus - Perfectly harmonized
Sample and viscometer identification
...with our thermostats
To allocate the stored measuring results, the user can enter 2-digit numbers to the ViscoClock plus
before measurement. These IDs – together with date and time – ensure an unambiguous assignment of
the flow times.
Our ViscoClock plus is perfectly harmonized with our thermostat baths. If needed we provide you with
perfectly matching ViscoClock modules..
Absolute viscosity
ViscoClock plus
To determine absolute kinematic viscosities, calibrated viscometers have to be used. To guarantee best
accuracy, viscometers which were calibrated by automatic measurement should be used. The constant
of automatic calibration can be slightly different in comparison to manual calibration, as the level of the
light barriers may not be identical to the position of timing marks.
Relative viscosity
Thermostat CT72/P
For determination of relative viscosities, calibrated as well as non-calibrated viscometers can be used.
For evaluation, the calibration constant is not required in this case.
