WISER II combines the MS-711N and MS-713 Spectroradiometers (MTI.AWS.EK.WII) to provide the most accurate outdoor solar spectral data.
All-weather, with temperature-controlled spectrometers, the MS-711N and MS-713 deliver improved stability & long-term reliability. They are accurately calibrated with traceability to international standards and are issued with a calibration uncertainty budget.
The MS-711N measures between 300nm and 1100nm, while the MS-713 covers the near-infrared (NIR) range between 900nm and 2500nm; together, the WISER II covers the spectral range from 300nm to 2500nm.
