MICROTOPS II is a 5 channel hand-held ozonometer for measuring total
ozone column easily, accurately and dependably. Direct solar ultraviolet radiation at 3
discrete wavelengths within the UV-B range is measured and stored. Optionally, the
MICROTOPS II can measure total water vapor (936 nm) and aerosol optical
thickness (AOT) at
1020 nanometers. MICROTOPS II features an accuracy comparable to much larger and more
expensive instruments. Optional GPS receiver facilitates field operation. This instrument is
also available in standard WMO or custom configuration for sunphotometry (5 channels
- see
Ordering).

Features
| High accuracy. The highest grade filters are embedded into a solid cast
aluminum housing which assures accurate, stable optical alignment. Low noise electronics
and a 20 bit A/D converter allow high linearity, resolution and dynamic range. |
| Ease of use. No computer knowledge is necessary to make measurements.
Just aim the meter at the sun, aligning the image of the sun with the cross-hairs and push
the button. In few seconds the measurement will be completed and the result stored in
memory. |
| Portability. A small hand-held device is all you need to perform
measurements. No additional computer is necessary. |
| Instantaneous results. The ozone and total water vapor calculation
algorithms are programmed into the MICROTOPS II and the final results of all stored scans
can be conveniently viewed on the LCD. The raw data is also stored to allow retrospective
adjustments of algorithms. |
| Non-volatile memory. The raw data collected by the MICROTOPS II, as
well as calculated results are stored in non-volatile memory. Each data point is annotated
with date, time, site coordinates, solar angle, altitude, pressure and temperature. |
| Low cost. By implementing the latest technology, instrument cost has
been brought well below that of comparable ozonometers, without sacrificing accuracy or
features. |
| Computer interface. Connection to a PC through a serial interface
(RS232) enables transfer of collected data. MICROTOPS
Organizer, a Windows-based software
automates data retrieval and archiving. |
