Airmodus - Model A20 - Condensation Particle Counter (CPC) - Datasheet

“It’s the small things that count.” Airmodus Ltd. www.airmodus.com Pietari Kalmin katu 1 F 1 00560 Helsinki, Finland Business ID: FI23103192                              A20 bCPC www.airmodus.com Airmodus Condensation Particle Counters are designed to count individual aerosol particles accurately from very low to high concentrations. They are ideal for ambient air monitoring as well as aerosol research. The A20 is a robust and reliable tool for aerosol particle measurements in all applications where precision and sensitivity is of the essence. It is a user-friendly tool for counting aerosol particles larger than 7 nm. A versatile particle counter The A20 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 A20 is also compatible with the Airmodus Particle Size Magnifier A10. Use the A10 when you want to study particles as small as 1 nm Benefits of the A20 - High statistics for low concentrations: the instrument is specially designed for precise particle counting and the sample flow is not diluted - High accuracy for high concentrations: up to 30 000#/cm3 in single-counting mode, for higher concentrations the Total Scattering Mode Correction is automatically applied - In addition to the easy to use touch screen, adjusting the settings and data logging is easy. User-friendly operation software is delivered with the instrument - All connections optimized for easy access  Airmodus Ltd. info@airmodus.com Pietari Kalmin katu 1 F 1 00560 Helsinki, Finland Business ID: FI23103192                              A20 bCPC Specifications www.airmodus.com *) Cut-off size in mobility equivalent diameter.
