HELOS & MYTOS
HELOS, the well proven laser diffraction sensor is the first system using one measuring principle (laser diffraction in the parallel laser beam) for the whole measuring range from 0.1 µm to 8750 µm. Two evaluation modes are offered: FREE: a parameter free solution basing on Fraunhofer diffraction and MIEE: basing on precision Mie theory extended to the full size range, as an option
It is the classical instrument for particle size analysis of dry and wet samples, i.e. of powders, suspensions, emulsions or sprays. It is entirely built to the specifications of ISO 13320 "Particle size analysis - laser diffraction methods" - and designed for absolute precision measurements to typically ±1% deviation with respect to the standard metre.
The classical approach for in-line dry particle size analysis from 0.25 to 3500 µm including dry dispersing and laser diffraction is based on MYTOS, the state of the art in-line laser diffraction unit. Automated on- and at-line options complete the MYTOS family to satisfy the demands of the process and application.
