SP2
Single Particle Soot Photometer

The Single Particle Soot Photometer (SP2) is laser-induced photometer manufactured by Droplet Measurement Technologies. SP2 provides measurements of black carbon (BC) mass content of individual aerosol particles as well as the optical and physical properties of the particles containing BC. SP2 can be utilized on airborne or ground-based platforms and can be deployed with a paired Humidified-Dual SP2 (HD-SP2). It can detect aerosol particles with a diameter size of 200-400 nm and can measure 25,000 particles/second.
