Met One 831

Description

Speck is an optical sensor that measures the current concentration of fine particles in the air. The default is a count-based concentration—the number of particles per liter of air (ppl). Alternatively, the Speck can report the fine particle concentration based on an estimate of particle weight (mass) where the units are micrograms per cubic meter of air (μg/m3).
