MS-720 portable spectroradiometer is designed to measure the spectral irradiance in the range from Visible to Near-Infrared. The MS-720 is mainly used for the data acquisition for geological features, vegetation, oceanography, remote sensing and other applications. MS-720 is a handheld sensor with an integrated LCD and an internal memory. Therefore, it is suitable for outdoors stand-alone measurements. A small-sized stable grating spectrometer with photo diode array is integrated. The data can be simply downloaded to a PC by using the MS-720 control software. Several scientific functions are incorporated (e.g calculate the integrated irradiance of a measured spectrum against a reference spectrum).
