Technical Specifications of the ViscoClock plus

1.1 Intended Use

The ViscoClock plus is an electronic viscosity measuring device.
Use only viscometers of the brand SI Analytics
The ViscoClock plus automatically measures the time which a liquid requires to flow from the upper to the
lower timing mark of the measurement bulb through the capillaries of the viscometer. You can measure all
transparent liquids – for which the viscometer used is suited according to its operating instructions – with a
temperature of - 40°C up to a max. of + 150°C.
The relevant regulations regarding the handling of the substances used have to be observed:
The Decree on Hazardous Matters, the Chemicals Act, and the rules and information of the chemicals
trade.
For the measurement of the relative viscosity, all calibrated or uncalibrated DIN, ISO, ASTM, Micro
Ubbelohde and Micro Oswald viscometers can be used.
To measure the absolute kinematic viscosity, you must use viscometers that have been calibrated
for automatic measurements!
As a principle, the measurement of the flow time should be performed in a transparent SI Analytics
thermostat bath in which the ViscoClock plus is fixed by the manual measurement insert of the bath and
which is suitable for the intended temperature range.
For tempering in the thermostat (tempering range: - 40 to + 150°C), the following tempering liquids are
permitted:
- Water
- Alcohol-water (e.g. ethanol, methanol)
- Glycerin
- Paraffin oil
- Silicone oil
- Glycol
For temperature ranges higher than 90°C, we recommend using silicone oils as a tempering liquid.
The ViscoClock plus must not be used for other work than the above-mentioned.
The manufacturer will not be liable for any damage resulting from this.
The ViscoClock plus must only be used by authorized persons whose training or knowledge
and experience ensure proper operation of the device and who are informed about the dangers!
On the part of the user it has to be ensured that the persons entrusted with the use of the ViscoClock plus
are experts in the handling of substances used in the environment and in the Device or that they are
supervised by specialized persons, respectively.
Not suitable for use in explosive environments!
Always attach the silicone cap perpendicular onto the ventilation tube! With a lateral load on the
ventilation tube, the glass tube may break!
Do not pump the sample liquid into the measuring sphere using the manual pump after
pressing the start key! Sample liquid will enter the unit via the ventilation tube. This results in damage
to the unit!
