HELOS | RODOS & Co. | Laser Diffraction | Particle Size and Particle Size Distribution from below 0.1 µm to 8,750 µm

The proven HELOS laser diffraction series – with its classical parallel beam laser diffraction set-up – offers a powerful technology for reliable particle size distribution analysis of powders, granules, suspensions, emulsions, sprays and numerous other particulate systems. A size range from below 0.1 µm to 8,750 µm is mastered.

In the early 1980s, Sympatec introduced a breakthrough innovation which was leading laser diffraction to another dimension: dry powder dispersion for even the finest, cohesive powders came true with RODOS. And with the R series of our laser diffraction sensor HELOS new benchmarks for precision and accuracy have been achieved. Latest improvements comprise enhanced application of parameter-free Fraunhofer evaluation down to the submicron regime (below 1 µm), the greatest measuring signal frequency for best resolution with range combination technology and more powerful evaluation modes (Fraunhofer & Mie).

The modular HELOS system design together with a great variety of dispersing and dosing units provides a flexible adaptation to the most diverse industrial and research applications:

Dry Applications
