“It’s the small things that count.” Airmodus Ltd. info@airmodus.com Pietari Kalmin katu 1 F 1 00560 Helsinki, Finland Business ID: FI23103192                              A23 bCPC www.airmodus.com Designed for vechicle emission measurements Airmodus A23 Condensation Particle Counter is a user-friendly tool for all applications where counting aerosol particles larger than 23 nm is a necessity. It fulfills the requirements of the Particle Measurement Protocol (PMP) for EURO 5/6. A versatile particle counter The A23 can be used both as a stand-alone instrument for measuring the total particle number concentration, and as a counter in different kinds of aerosol measurement systems. It is easy to use and handle. All settings can be quickly adjusted from a handy touch screen, which also displays the current concentration reading and instrument diagnostics. The A23 is also compatible with the Airmodus Particle Size Magnifier A10. Benefits of the A23 - The saturator is made of robust and inert stainless steel in order to ensure stable operation - Narrow pulse width for higher counting accuracy - Easy to use touch screen - Improved usability and design: all connections optimized for easy access PMP requires A23 Dp50% (±12%) = 23 nm ± 1 nm ü? 23 nm Dp>90% = 41 nm ± 1 nm ü? very sharp cut-off curve Linear concentration response between 0 - 10 000 #/cm3 ü? 0 - 30 000 #/cm3 Airmodus Ltd. info@airmodus.com Pietari Kalmin katu 1 F 1 00560 Helsinki, Finland Business ID: FI23103192                              A23 bCPC Specifications www.airmodus.com *) Cut-off size in mobility equivalent diameter.
