The DustMon RD 100 from Retsch GmbH is a laboratory device used for dust measurement.
DustMon RD 100 is an independent measuring system to determine the dust content in
powders and granulates. DustMon RD 100 is a newly-designed measuring system based on
the principle of light attenuation. The robust design and simple operation guarantee fast,
reliable results under even the toughest conditions.
The DustMon RD 100 is offered with a white light source (LED).
The DustMon RD 100 can be used as a stand-alone measuring system or without PC and
DustMon software. The measurement can be started using the integrated display, and this
display also shows the results at the end of the measurement. When connected to a PC, the
results can be saved and printed out.
The DustMon RD 100 comprises the following components:
•
Sample holder
•
Tube
•
Sample collection receptacle
•
Light source
•
Detector
The sample is placed in the sample container, the flap opens immediately (or with a delay
depending on the setting defined by the user), then the measurement begins. The dust present
in the product rises and gets between the light source and detector, thereby causing light
attenuation. The light attenuation is directly related to the dust concentration in the sample to
be measured.
The DustMon software produces a measurement based on a dust index scale, where the dust
index value is determined as follows:
Maximum value measured
Value measured after 30 seconds
Dust index = maximum value me value measured after 30 seconds
