Product details
MICROTOPS II is a 5-channel handheld ozone meter used for precise measurement of total ozone column volume. It can measure and store 5 non continuous wavelengths of direct ultraviolet radiation from the sun within the UVB ultraviolet range. By utilizing the 936nm and 1020nm channels, MICROTOPS II can also measure total water vapor and aerosol optical thickness (AOT).
Compared to large and expensive instruments, MICROTOPS II has a 2% accuracy. Optional GPS receiver, suitable for field operations. For the measurement of ozone column, the instrument adopts a standard WMO structure.

Main features:
uHigh precision Internally implanted with the highest standard optical filters to ensure precise and stable optical collimation. Low noise electronic devices and a 20 bit A/D converter ensure high linearity, high resolution, and high dynamic range.
uEasy to apply No computer knowledge is required for measurement. Just aim the instrument at the sun, align the crosshairs with the sun image, and press the button. The measurement can be completed in a few seconds and the results will be stored in the memory.
uPortability Only a small handheld device is needed to complete the measurement, without the need for a computer.
uInstantaneous results The calculation algorithms for ozone and water vapor are integrated into MICROTOPS II, and the final stored results can be easily displayed on an LCD monitor.
uNon volatile memory Collect raw data from MICROTOPS II and store the calculated results in memory. Each data point is labeled with time, date, solar angle, altitude, location coordinates, atmospheric pressure, and temperature.
uComputer interface Connect to a PC via a serial interface (RS232) to transmit the collected data. MICROTOPS Organizer is a Windows based software used for automatic data retrieval and archiving
