FDS 18

  • real-time measurement of PM2,5
  • Monitoring of fine dust concentrations in ambient air and/or at workplaces
  • optical sensor including fitting with clip system, therefore easily exchangeable
  • active and automatic zero point setting
  • active air suction
  • Integrated pre-separator for particles > 2,5 µm
  • noiseless operation
  • network-compatible


By means of the FDS 18 it is possible to determine the
current particulate matter concentration of the environment
and make out health hazards.
The continuous monitoring of the air quality is usable
indoor and outdoor in the environment and at work
