Unique & all-weather, the MS-711N DNI is a new generation grating spectroradiometer designed to provide the most accurate direct solar spectral data outdoors.
MS-711N DNI
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.
Key Features:
- Robust design, made for outdoor solar research
- High optical resolution <7nm
- Operating temperature range -10 to 50°C
- Temperature controlled detector core
- NIST Traceable calibration

Contrary to popular belief, Lorem Ipsum is not simply random text. It has roots in a piece of classical Latin literature from 45 BC, making it over 2000 years old. Richard McClintock, a Latin professor at Hampden-Sydney College in Virginia, looked up one of the more obscure Latin words, consectetur, from a Lorem Ipsum passage, and going through the cites of the word in classical literature, discovered the undoubtable source. Lorem Ipsum comes from sections 1.10.32 and 1.10.33 of “de Finibus Bonorum et Malorum” (The Extremes of Good and Evil) by Cicero, written in 45 BC. This book is a treatise on the theory of ethics, very popular during the Renaissance. The first line of Lorem Ipsum, “Lorem ipsum dolor sit amet..”, comes from a line in section 1.10.32.
The standard chunk of Lorem Ipsum used since the 1500s is reproduced below for those interested. Sections 1.10.32 and 1.10.33 from “de Finibus Bonorum et Malorum” by Cicero are also reproduced in their exact original form, accompanied by English versions from the 1914 translation by H. Rackham.
