The new generation grating spectroradiometer MS-711 DNI is designed to provide the most accurate direct solar spectral data outdoors. The MS-711 DNI is a unique all weather sensor, without any moving parts. The detector core is temperature controlled to provide accurate irradiance measurement data within the spectral range from 300nm to 1100nm (UV-Visible-NIR).

MS-711 DNI is accurately calibrated with traceability to the International Standards and issued with a calibration uncertainty budget. The rugged optical design of the diffusor and input optics make the MS concept superior to any fiber optic spectroradiometer which will be susceptible to mechnical vibration and handling. The MS spectroradiometers are designed for permanent installation, but are perfectly suited as a traveling reference.

MS-711 DNI has a compact fixed collimating tube with Quartz window and window heater. The sensor need to be attched to the STR-21G or STR-22G sun tracker for automatic tracking. A robust Aluminium mounting plate keeps the sensor in correct position.

MS-711 DNI has a separate power supply unit and can be controlled through RS232 / 422 by a PC or data logger. The PC software provides different functions for operating, data management and visualisation. Through the open command protocol of the defined system control functions, software can be developed by the individal user. Measuring spectral irradiance is a must to understand the effect of the non-uniform energy distribution of the sun. Since the solar spectrum varies as a function of air-mass and composition of the atmosphere, the MS-711 DNI reveals those details. While thermopile pyrheliometers and pyranometers are most suitable to quantify the total DNI or global radiation (W/m2), spectroradiometers give detail about the energy distribution (W/m2/nm), which is most important for PV or CPV cell research and performance analysis.
