Model 540 Microtops II® Sunphotometer

back

Model 540 Microtops II® Sunphotometer is a light weight, portable 5 channel instrument for measuring aerosol optical thickness, direct solar irradiance, and water vapor column easily, accurately and dependably.

 

Description

This multi-spectral instrument is designed to measure direct solar irradiance at all selected wavelengths. It then uses this information to provide atmospheric properties, such as aerosol optical thickness and water vapor column.

 

Standard wavelengths to choose from are 340nm, 380nm, 440nm, 500nm, 675nm, 870nm, 936nm, and 1020nm. If your research is focused in the longer wavelengths, then we recommend the 675nm, 870nm, 936nm or 1020nm filters.

 

If your research requires water vapor column measurements, then we recommend either the 936nm and 1020nm pair or the 870nm and 936nm pair. The unit features accuracy comparable to much larger and more expensive instruments.
