Rion VT-05/VT-06 Viscotester
The Rion VT-05/VT-06 Viscotester provides a unique objective and cost-effective means of directly measuring the viscosity of liquids/fluids. The viscosity of many substances is of crucial importance yet, up to now, measurement of this quantity has often been achieved through indirect, complicated and/or expensive methods. Application areas include chemicals, paint, petrochemicals, adhesives and foodstuffs.
The VT-05 ( for lower viscosity fluids ) and VT-06 ( for higher viscosity fluids) consist of a hand-held ( or it can be mounted on a stand) meter with an integral digital display with a rotor that is connected to the rear of the device. With the meter held ( approximately ) horizontally, the appropriate rotor is submerged in the fluid to be tested. The meter will then give a direct digital readout of the viscosity of the fluid in millipascal/decipascal seconds ( the SI unit for Viscosity )
The VT-05 can measure up to 300 mPas. The VT-06 can measure up to 4000 dPas.
Examples of typical viscosity ( at 23 °c ) :
Milk - 2.6 mPas;
Olive Oil - 71 mPas;
Tomato Ketchup - 43 dPas;
Toothpaste - 320 dPas.
