MICROTOPS II is a 5-channel handheld sunphotometer for precise measurement of aerosol optical depth. It measures and stores 5 discrete wavelengths of direct solar radiation. MICROTOPS has the same accuracy as other larger and more expensive instruments. The optional GPS receiver facilitates field measurements. The user can select 5 of the 8 WMO wavelength filters or specify up to 5 custom wavelengths.
Product Introduction: MICROTOPS II Is a 5-channel aerosol optical thickness precision measurement Handheld sun light meter . Direct solar radiation can be measured and stored at 5 non-continuous wavelengths. MICROTOPS has the same accuracy as other large and expensive instruments. The optional GPS receiver provides convenience for field measurements. The user can select 5 from 8 WMO wavelength filters or specify up to 5 custom wavelengths. MICROTOPS II sunphotometer can measure aerosol optical depth and solar direct radiation at all selected wavelengths. The wavelengths of 936+870+1020nm, 936+870 and 936+1020 can be used to measure water vapor column.

Key Features:
High Precision: The highest standard filters are implanted inside to ensure accurate and stable optical alignment. Low noise electronic devices and 20-bit A/D converters ensure high linearity, high resolution, and high dynamic range.
Easy to use: No computer knowledge is required to take measurements. Simply point the meter at the sun, align the crosshairs with the sun image, and press a button. The measurement is completed in a few seconds and the result is stored in memory.
Portability: Measurements can be performed with just a small handheld device, no computer required.
Instantaneous results: Ozone and water vapor calculation algorithms are programmed into MICROTOPS II and the final stored results can be conveniently displayed on the LCD display.
Non-volatile memory: MICROTOPS II collects raw data and stores calculation results in memory. Each data point is labeled with time, date, sun angle, altitude, location coordinates, atmospheric pressure and temperature.
Low cost: Due to the use of the latest technology, it has a more competitive price compared to other products, but its accuracy and other features are outstanding.
Computer Interface: The acquired data can be transferred to a PC via a serial interface (RS232). MICROTOPS Organizer is a Windows-based software for automatic data retrieval and archiving.
