HTabsOverviewThe PCASP-100X is an airborne optical spectrometer that measures aerosol particles in the 0.1 µm to 3 µm range. Key Features Single particle resolution Get unmatched sensitivity and specificity in real-time measurements of aerosols. Direct measurement Enable direct measurement of the air stream with the leading cannister-based aircraft instrument. Unmatched efficiency Power your research with elimination of dead-time losses, plus continuous monitoring of multiple housekeeping variables. Advanced control Get user-programmable sample rates, number of channels, and channel size thresholds.
