Airborne particle counter without display A20-CEN pgCPC

opticalcondensationmicrobial

Overview
Condensation Particle Counters (CPCs) detect and count ultrafine particles by growing nanoparticles in a saturator–condenser system to optically detectable sizes. The A20-CEN pgCPC is a CEN-compliant CPC using odorless, non-flammable Propylene Glycol (PG) as the working fluid. It delivers CEN 10 nm performance and provides higher nominal sample flow (1.05 lpm) compared with smaller models, improving counting statistics in odor-sensitive or butanol-restricted environments. The instrument can operate as a standalone monitor or as the detector CPC in A-SMPS systems.

Applications

• CEN-compliant ambient and laboratory monitoring where butanol is restricted
• Cleanroom and controlled-environment particle monitoring
• Aerosol research, SMPS detector, and bioaerosol studies

Features and benefits

• Safe working fluid: odorless, non-flammable Propylene Glycol (PG)
• High nominal sample flow: ~1.05 lpm (full flow through optics)
• Fully open calibration algorithm
• No catalytic vapour remover required
• Advanced signal diagnostics and instrument health monitoring
• CEN-compliant (EN 16976:2024)
• New inlet BlockSafe system; minimal cross-sensitivity with co-located gas monitors
