This Labman machine is Rotational Digital Direct Reading Viscometer to measure absolute viscosity of Newton Liquids as well apparent viscosity of non – Newton liquid featured by high flexibility reliable Test result, easy operation and good appearance. The Salient Features of the viscometer are auto range function, selectable speed direct viscosity reading and temperature display with big ultra-bright backlight LCD Display the High-Power Optics produces fine electron probe for both observation and analysis. The aperture angle control lens maintains a small probe diameter even at a larger probe current. Using both techniques, this machine is suitable for a wide variety of analysis with EDS.
