Xylem Si Analytics ViscoClock Manual De Instrucciones página 21

1.1 Description
The Viscosity Measuring Unit ViscoClock automatically measures the flow time of a liquid in a SI Analytics
GmbH viscometer to determine the relative and kinematic {absolute) viscosity. The time measured is the
time which a liquid requires to flow from the upper to the lower measurement mark of the measurement
bulb through the capillaries of the viscometer. Measurement is done in a SI Analytics GmbH thermostat
bath (SI Analytics GmbH product Information), e.g. transparent thermostats of the CT 72 type series. The
thermostat change is done outside the thermostat bath.
The Viscosity Measuring Unit ViscoClock consists of a stand tor accommodating the viscometer and the
electronic measuring unit. The two measurement marks are integrated in the plastic stand (PPA). The
e!ectronic measuring unit is built into a polypropylene casing. Owing to the use of heat-carrier liquids as
bath media, co!our changes may occur on the stand which, however, do not affect the measurement
accuracy.
