Air particle counter A20

digitalcondensation

Overview
The A20 is an Airmodus condensation particle counter (CPC) engineered for accurate counting of individual aerosol particles from very low to high concentrations. Suitable for ambient air monitoring, aerosol research and regulatory measurements, the A20 counts particles larger than 10 nm (optionally configurable cut-off 3–23 nm) and offers high sensitivity and precision while maintaining a non-diluted sample flow.

Key features

• Counts individual particles up to 500,000 #/cm³
• Accurate particle counting across a wide concentration range
• Extremely low operational noise

All Airmodus CPCs feature

• Easy-to-use touchscreen interface
• Fully transparent algorithm
• Analog input and output
• Advanced pulse diagnostics
• BlockSafeTM flood prevention
