Mastersizer 3000+ Ultra

The Smartest Way to Measure Particle Size

The Mastersizer 3000+ Ultra is the most sophisticated device for measuring particle size and size distribution using laser diffraction. This model has the broadest measurement range (0.01 - 3500 um) and facilitates automation. The digitally upgraded Mastersizer Xplorer has a full suite of artificial intelligence-powered workflow capabilities, including the new Size Sure measurement mode.
