Solar Light’s Model 540 Microtops II® Sunphotometer is a lightweight,
portable 5-channel Sunphotometer for measuring aerosol optical thickness,
direct solar irradiance, and water vapor column easily, accurately and dependably.
Although packaged in a conveniently small handheld chassis, this instrument’s
accuracy is comparable to much larger and more expensive instruments. The
Model 540 Microtops II® Sunphotometer has been the gold standard in the
professional atmospheric research community for years. It is heavily relied upon
by the world’s leading weather stations for scientific studies, pollution and
environmental monitoring, photobiology research, and much more!
