“It’s the small things that count” Designed for vehicle 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. The A23 CPC is compliant with the Particle Measurement Protocol (PMP) for EURO 5/6. It fulfills the requirements of UN/ECE R49 and UN/ECE R83. 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 Regulation requirements Linear concentration response and counting accuracy of ±10% across the range of single particulate counting mode Operates under full flow operating conditions Data reporting frequency ≥0.5 Hz Airmodus Ltd.
