WISER I Spectroradiometer

The WISER I Spectroradiometer configuration, combining the MS-711N, measuring the spectral range from 300nm to 1100nm (UV-Visible-NIR), and the MS-712 for the near-infrared (NIR) range between 900nm and 1700nm, is designed to provide the most accurate outdoor solar spectral data.

With temperature-controlled sensor units and NIST traceable calibration, the WISER I delivers improved stability and long-term reliability, suitable for all-weather conditions and continuous outdoor use, with an operational temperature range of -10 to 50°C.

Often installed in fixed locations for meteorological, plant science, photovoltaic research, and material analysis applications, the WISER I is also suitable for use as a travelling reference, with separate power supplies for both sensors, a calibration uncertainty budget, and software, including 'Nami', for sensor management, data analysis, and visualisation.
