Viscometers ViscoClock plus

SKU: 285417900
Overview Documentation & Tools

Electronic timing unit for glass capillary viscometers

The SI Analytics ViscoClock 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.

Product Features
  • Automatic and precise flow time measurement for a low price
  • Suitable for SI Analytics® Ubbelohde, Micro Ubbelohde and Micro Ostwald
  • 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

The SI Analytics 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 fl ow times and additional information: date, time, sample ID and viscometer ID.

Automatic measurement of flow times

The ViscoClock 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 fl ow time measurement.

Properties and materials

The ViscoClock plus can be used for measuring temperatures ranging from -40 °C to 150 °C. The stand of the ViscoClock plus is 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 fl ash 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.
