Kinematic Viscosity: SVM 3000 Stabinger Viscometer
The SVM 3000 Stabinger Viscometer measures the dynamic viscosity and density of oils and fuels according to ASTM D7042. From this result, the viscometer automatically calculates the kinematic viscosity and delivers measurement results which are equivalent to ISO 3104 or ASTM D445. The Stabinger measuring principle with Peltier thermostat enables an incomparably wide viscosity and temperature range with a single system. SVM 3000 is quick, compact and energy-saving, versatile in use, with only small amounts of sample and solvents required. This makes it the most efficient high-precision viscometer on the market. The SVM 3000 Stabinger Viscometer is a rotational viscometer with a cylinder geometry. It is based on a modified Couette principle with a rapidly rotating outer tube and an inner measuring bob which rotates more slowly. The instrument is named after Dr. Hans Stabinger, who developed it together with his team at the Laboratory for Measuring Technology in Graz/Austria. It is the first instrument to combine the required precision for ASTM D7042 and measurement of the viscosity index according to ASTM D2270/ISO 2909 in a compact, lightweight benchtop device. SVM 3000 uses a new, patented measuring principle (EP 0 926 481 A2).
