A unique all-weather sensor, the MS-711N features a temperature-controlled detector, ensuring optimum performance in hot and cold conditions ranging from -10 to 50°C. Measuring the spectral range from 300nm to 1100nm (UV-Visible-NIR), the MS-711N comes with NIST traceable calibration, a calibration uncertainty budget, and is compatible with EKO STR-Series sun trackers.

The MS-711N can be set up in an albedometer configuration for measuring spectral albedo in bifacial PV installations and is part of both the WISER I system, covering the spectral range from 300nm to 1700nm (UV-VIS-NIR), and the WISER II system covering 98% of the integrated solar-terrestrial spectrum, from 300nm to 2500nm.

The new generation grating and rugged optical design of the diffusor and input optics in the MS-711N make it superior to any fiber-optic based spectroradiometer by eliminating common issues with mechanical vibration and handling; ideal for permanent installation or as a travelling reference.

The MS-711N has a separate power supply and can be controlled through RS232 / 422 via a PC or data logger. EKO also provides software options for device and data management and visualisation.

EKO Spectroradiometers deliver top-tier spectral measurements and detail about energy distribution (W/m2/nm), essential for effective PV or CPV cell research and performance analysis.
