MICROTOPS II® Ozonometer is a 3 or 5 channel hand-held ozonometer for measuring total ozone column easily, accurately and dependably.
Using Model 520, direct solar ultraviolet radiation at 3 discrete wavelengths within the UVB range is measured and stored. Model 521 can also measure total water vapor and aerosol optical thickness (AOT) using both 936 and 1020 nanometer channels.
MICROTOPS II® Ozonometer features a 2% accuracy which is comparable to much larger and more expensive instruments. An optional GPS receiver facilitates field operation. This instrument uses standard WMO configuration for measuring the ozone column.Uses Measures Ozone Column, Total Water Vapor and Aerosol Optical Thickness (AOT).
