The UHSAS-G is an optical-scattering, laser-based aerosol particle spectrometer for sizing particles in the 0.06 µm to 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-G ideal for aerosol research and filter testing. Get an on-board computer, built-in monitor, and powerful LabVIEW-designed software for easy, real-time data analysis.
