Minivis 445 – Portable Micro-Viscometer Combines Rolling Ball Viscometer and Advanced Density Meter

Jan 11 2008 Read 2287 Times

Grabner Instruments launches MINIVIS 445, an automatic, portable Micro-
Viscometer for the determination of viscosity of all kinds of fuels, oils and other liquids in the laboratory or in the field.
MINIVIS 445 combines a rolling ball viscometer with an advanced density meter, an automatic filling system and a very fast temperature control.
The compact unit was designed for the precise determination of dynamic and kinematic viscosity over a wide temperature and a viscosity range of
0.2 to 3000 cSt (mm2/s) and relies on a built-in density meter.
Built-in Peltier elements provide temperature control, eliminating the need for large water baths and allowing for quick determination of viscosity index, which is automatically measured and calculated. MINIVIS 445 is fully automated, portable and easy to operate, thus making the instrument the first choice for precise viscosity measurements in heavy duty environments and for applications in mobile laboratories.
The instrument incorporates reflection sensors which make it possible to cover a wider range of applications, from transparent to very opaque samples such as used or heavy oil. Its measurement cell is easily accessible, eliminating the cleaning problems associated with other viscometers. The sample remains in the instrument, while the cell temperature changes. Users appreciate the unit’s easy handling and automatic sample feeding.
