A20-HF High-Flow CPC

High flow rate condensation particle counter

The Airmodus A20-HF is a high-flow Condensation Particle Counter with a 7 nm cut-off and 2.3 lpm sample flow - 2.3x the sample volume of a standard A20 CPC. The increased flow delivers significantly more particles to the detector per unit time, making the A20-HF the instrument of choice for cleanroom contamination monitoring and Eddy Covariance flux measurements. With 10 Hz data logging and raw pulse output available, the A20-HF provides the time resolution required for turbulent flux calculations. Custom cut-off calibrations between 4 nm and 10 nm are available on request.
