Product Description

The Koehler Master Series Rotational Viscometer 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. Includes carrying case. SOFTWARE IS AVAILABLE AT AN ADDITIONAL COST

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.

Viscometer gathers measurement data This software allows to create a user
& stores in its internal memory (set customized programs. After downloading a
measurement with the keypad). More program from the computer, up to 800 data
than 10,000 data points can thus be points can be collected and automatically
stored inside the viscometer. Then stored in the DV-III+ (computer skills are
use this software to export the stored needed)
data in Microsoft Excel format (no
computer skills needed)
