"For solar spectral research, we believe only one measurement concept can be the best. The combination of MS - 711 and MS - 712, called WISER 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 300 nm and 1100nm, and MS - 712 covers the near infared (NIR) range between 900nm and 1700nm. Both spectroradiometers are accurately calibrated with traceability to the international standards and issued with a calibration uncertainty budget.","• Continous Outdoor Measurements • Instant Measurement Of Full Spectrum 300nm - 1700nm • Excellent Long Term Stability Of Detector Array • Low Temperature Dependency Of Detector • Fully Controllable By PC And Datalogger • High Quality Calibration And NIST Traceable"
