| KOEHLER K447-MX Dynamic Viscosity by Master Series Rotational Viscometer |
| Test Method Determines the dynamic viscosity of a substance by the rotation of a specified spindle within the sample at the speed giving the maximum torque reading on the viscometer. The resulting torque reading is used to calculate the viscosity of the substance. Master Series Rotational Viscometer • Master Series viscometers, monitored by Master Series Rotational Viscometer Software, offer a wider and unique range of rheological applications. • Touch key board with 12 keys • Direct readout on a graphic display • Data displayed Selected speed: r.p.m. Selected spindle: SP Viscosity Reading: cP (mPa·s) or cSt Percentage of full scale: % Sample temperature: °C or °F Shear Rate (with coaxial spindles): SR (s-1) Shear Stress (with coaxial spindles): SS (N/m2) Density (introduced by the user): g/cm3 Step Program Status Analyze & visual characteristics (flow curves) • Viscosity reading: dynamic viscosity (cP or mPa·s) or kinematic viscosity (cSt) • Program features: Time to torque: target torque pre-setting device Time to stop: target time pre-setting device 10 working memories Customizable options Programmable Multistep Ramp • AUTO-TEST with sound and visual malfunction alarm • AUTO-RANGE function • Temperature reading by PT100 • User-enabled viscosity and temperature calibration • 10 language options • AISI 316 stainless steel spindles Master Series Rotational Viscosity Software • Complete viscometer control • Easy to use. All programs eliminate user errors when programming the instrument to collect data. • Provides instantaneous viscosity flow curves when performing new experiments, with definable parameters • Clear view of program options using flanges • Definable graphics and zoom function • Different types of experiments can be programmed: simple curves, ramps, and multi-step • All experiments are recorded in different databases to be able to consult them anytime • Experiment documentation with name, number, and additional data • In order to compare different flow curves, up to 4 experiments can be plotted simultaneously • Over 12 different charts can be obtained The Master Series Rotational Viscosity Software is designed to program the Master Series Viscometer and is a powerful key to document and study the viscosity behavior of fluids. The Master Series Rotational Viscosity Software is capable of graphing simple curves, ramps and “multi-step” curves allowing the user to study trends and the behavior of different materials. A powerful graph key assists the user to easily design flow curves required. |  Click on the image to view a larger photo of the instrument. |
