Attention:
Please note that operations of the SP2 requires experienced scientific staff on board the aircraft.
Summary
The UHSAS is an optical-scattering, laser-based aerosol particle spectrometer for sizing particles in the 0.06 – 1 µm range. The instrument counts particles in up to 100 user-specified sizing bins, with a resolution as fine as 1 nm/bin. This high sensitivity makes the UHSAS ideal for aerosol research and filter testing.

Components
The SP2 system consists of the photometer unit, which is installed in a rack. It is connected via tubing to an air inlet. An external SP2 pump ensures sustains the vacuum in the lines. Additionally, drying cartridges can be installed in the airflow. Air flow meter are connected to the system to visually check on the air flow.
