Interchangeable measuring cell modules enable analysis of particles in virtually any state: liquids, powders, slurries, aerosols, pastes, thin lms and emulsions. Special cells facilitate the measurement of high concentrations. I-mage 400 covers a wide size range: from 0.4 to 3600 microns by changing only a single lens. With the Video Microscope, shape measurements on hundreds of thousands of particles from 1 micron to as large as 4,5 mm can be obtained in minutes. The I-mage features high optical quality with high contrast image that facilitates the denition and measurement of even low contrast objects.
