For solar spectral research, we believe only one measurement concept can be the best. The combination of MS-711 and MS-712, called WISER I is the reference in the market and designed to provide the most accurate solar spectral data outdoors.
The MS-711 and MS-712 spectroradiometer are unique all weather concept spectroradiometers with no moving parts and temperature controlled spectrometers. The MS-712 can be used stand alone, but in combination with the MS-711 it covers the spectral range from 300nm to 1700nm. MS-711 measures in the range from 300nm and 1100nm, and MS-712 covers the near-infrared (NIR) range between 900nm and 1700nm. Both spectroradiometers are accurately calibrated with traceability to the International Standards and issued with a calibration uncertainty budget.
