Fotometer-Calibration-System FCS 248 for aerosol generation from liquids, ideal for calibration of aerosol fotometers and particle counters

The FCS 248 Fotometer-Calibration-System 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 is 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 particle concentration can be varied over a wide range.
