The proven HELOS series – with its classical laser diffraction set-up deploying a parallel beam – offers a powerful technology for particle size analysis of powders, granules, suspensions, emulsions, sprays and numerous other disperse systems. A size range from below 0.1 µm to 8,750 µm is mastered. The modular system design, together with a great variety of dispersing and dosing units, provides a flexible adaptation to the most diverse industrial and research applications.
