FCS 248 – Calibration System for Aerosol Photometers and Particle Counters

The Calibration System FCS 248 generates stable and reproducible test aerosols for calibration of photometers and particle counters. The calibration is based on the comparison of three devices to be calibrated. The centerpiece is a special aerosol generator, which is controlled by additional instrumentation. As an aerosol substance DEHS used. The atomization of the aerosol substance is made using special two-fluid nozzles. By an adjustable carrier air flow and precise needle valves, the aerosol concentration can be varied over a wide range.

 

  • Adjustable within a wide aerosol concentration range (DEHS)
  • Carrier air flow up to 100 Nl/min
  • Compact housing for mobile use
  • Battery operation possible
  • Possibility to connect up to three devices to be calibrated
  • Calibration of photometers for concentrations up to 1 g / m³ (DEHS)
  • Calibration of particle counters and aerosol spectrometers
