FCS 248
Fotometer Calibration System FCS 248 for aerosol generation from liquids, ideal for calibration of aerosol fotometers 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.\r\nThe 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.
