TSI's Model 3025A Ultrafine Condensation Particle Counter is a continuous-flow particle counter that detects particles as small as 3 nm in diameter. A sheath-air flow design optimizes this CPC's efficiency for detecting ultrafine particles, for concentrations up to 105 particles/cm3. The 3025A responds quickly to concentration changes. It includes a front-panel display for viewing particle counts or concentration data. An internal microprocessor and built-in serial port simplify data collection and storage.
