What it does:

MAGIC measures the number concentration of airborne particles larger than 5 nm in diameter.

How it works:

Moderated
Aerosol
Growth with
Internal water
Cycling

Ultrafine particles are enlarged by water condensation to form micrometer-sized droplets that are detected optically. MAGIC’s unique feature is to capture the water vapor needed for supersaturation internally, eliminating the need for internal water reservoirs.

Features:

• light-weight & portable
• lower threshold <6 nm
• motion-tolerant: shaken, tipped, or jostled
• tolerates inlet pressure variations
• battery operable for ~ 8hrs.
