Aerosol Counting System

The ACCESS suite of instruments is an ideal measurement solution for applications like Unmanned Aerial Vehicles (UAV) requiring small size, portability, low weight, and low power usage. ACCESS includes four miniaturized measurement modules that can fit on a single UAV: a small Mixing Condensation Particle Counter (MCPC) for real-time total number concentration observations, an Optical Particle Counter (OPC) for number size distribution measurements between 0.1 and 10 μm, a Single-channel Tricolor Absorption Photometer (S-TAP) for light absorption and black carbon measurements, and an eight-channel filter sampler for off-line chemical composition measurements.
