Item#L3 Microtrac Laser Diffraction Particle Size Analyzer
Manufactured by Microtrac, Model S3500. Measurement capability from 0.02 to 2800 microns. Wet and dry measurements. Complete and in very good shape. The unit operated, but needs a communication board and a hardware upgrade. Microtec has quoted these items at around $8-9K. They are selling as is because of this need. New these are quite expensive.
