Field Calibration System FCS 249

The FCS 249 is a mobile system for the defined generation of reference and test aerosols, which can be varied with respect to the particle number concentration in a wide working range.

Standards

In particular, the FCS 249 is suitable for the validation of condensation particle counters (CPC) or electrical aerosol monitors, which are applied for the particle number concentration measurement in exhaust gases of vehicles according to the "AU-Geräte Kalibrierrichtlinie (German exhaust emission test equipment calibration guideline)".

Benefits

• complies with all NaCl test aerosol requirements of the German exhaust emission test equipment calibration guideline
• mobile system (portable, no compressed air required, power supply needed)
• suitable for use in harsh workshop conditions
• suitable for commercial low-concentration NaCl solutions
• reactionless aerosol sampling
• 7 via touch screen adjustable points of particle concentration (with trim function)

Applications

• calibration and validation of aerosol measuring devices
• comparative measurements of particle counting devices for periodical technical inspection of vehicles (PTI)
• validation of mobile measuring devices (PEMS - portable emission measurement system) for exhaust gas testing in road traffic
