The ViscoCIock plus is an electronic timing unit for glass capillary viscometers used to determine kinematic and relative viscosity. 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.
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.

Advantages
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

Main features
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.

Absolute viscosity
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
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.
