Laboratory viscosimeter QVis 01/L

The laboratory viscosimeter QVis 01/L is suited for different applications: Within the reasearch laboratory, the viscosimeter allows an optimization of the development of fluids and in the test field a quick and easy quality control is facilitated.

Application

The handling of this type of viscosimeter is very simple and the required set-up time was reduced to a minimum. Specific measuring vessels are not needed and no problems with filling up narrow gaps or capillaries arise. As soon as the top of the measuring head (quartz and temperature sensor) is immersed into the measuring fluid, the QVis 01/L carries out accurate viscosity measurement in a large measuring range (1 to 10.000 mPas).

Composition

A compact table casing encloses the basic unit of the laboratory viscosimeter. The ergonomically shaped measuring head is attached to the basic unit by means of a flexible plug connection. For the optional connection of the QVis 01/L to a control computer (standard PC or laptop), a comfortable software program is included in the delivery, which allows the automation of the measuring procedure and the processing of the data. A standardized interface RS 232 enables the user to control a temperature unit or other elements. The RS 232 furthermore provides the user with the analog values for the viscosity (optionally also the temperature).
