Condensation particle counter for number concentration up to 104 particles/cm3 (single count mode) and 107 particles/cm3 (photometric mode)

The Palas® UF-CPC 50 is a butanol-based nanoparticle counter with high efficiency. It measures the number concentrations of ultrafine particles (UFP) in aerosols. Model 50 is designed for concentrations of up to 104 particles/cm3. Thus, it is ideally suited for measuring the lowest concentrations alone or as part of an overall system for measuring the size distribution and concentration of, e.g., synthetically produced aerosols (Scanning Mobility Particle Spectrometer / Mobility Particle Size Spectrometer).

The patented evaporator and condensation module is maintenance-free. This allows continuous operating times of up to one year - so far, unique.
