MS-711N DNI Spectroradiometer
Unique & all-weather, the MS-711N DNI is a new generation grating spectroradiometer designed to provide the most accurate direct solar spectral data outdoors.
A unique all-weather sensor, the MS-711N DNI Spectroradiometer is designed to provide the most accurate direct solar spectral data outdoors and 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 DNI comes with NIST traceable calibration and a calibration uncertainty budget.
The MS-711N DNI has a compact, fixed, collimating tube with a Quartz window and window heater and can be attached to the STR-21G or STR-22G sun trackers using a robust aluminium mounting plate for automatic tracking.
The new generation grating and rugged optical design of the diffusor and input optics in the MS-711N DNI 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 DNI 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.
- Robust design, made for outdoor solar research
