Heubach Dust Meter Type I (Gen 3)

The Type I is the most versatile. It functions by the method of the rotating drum and performs according to the measuring criteria set out by ESTA and Euroseeds for the Heubach dust reference values.

​

A sample is placed into the stainless steel drum, which then rotates at variable speeds, from 0-60 rpm. A controlled and constant airflow (0-40l) carries airborne dust particles out of the drum, through the coarse particle separator where coarse particles are segregated, and the remaining airborne particles are collected by a micro glass fiber filter at the end. The filter housing (<80g) can be weighed as a whole on any standard laboratory balance before and after the measurement. The gravimetrical difference is then put into relation to the sample size and thereby describes the dustiness potential of the material.
