MS-720 Spectroradiometer

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).


  • MS-720 is portable (WI00 x Dl60 x H60mm. 720g) and suitable for outdoor measurement. The operation is easy with the integrated LCD and the tact switch.
  • A stable diffuser, grating spectrometer and diode-array are adopted. MS-720 is highly reliable because there are no movable parts which could affect the measurement accuracy. MS-720 software automatically deterrnines the exposure time to perform the best measurement.
  • Automatically displays Irradadiance (W/m2), Luminance (lumen), PAR (µmol/m2/s)
