Microtops II Sunphotometer
Features
The Microtops II sunphotometer is a 5 channel hand-held instrument for
measuring the atmospheric column easily, accurately and dependably.
The Facility's Microtops II sunphotometers have been configured with
five filters for the determination of aerosol optical thickness (AOT),
including filters at 936nm and 1020nm for the measurement of total
water vapor.
Microtops II features an accuracy comparable to much larger and more
expensive instruments.
FSF can now offer four Microtops II sun photometers for loan or hire.
Please contact the FSF Equipment Manager for more information.
