제품특징

For solar spectral research, we believe only one measurement concept can be the best. The combination of MS-711 and MS-712, called WISER is the reference in the market and designed to provide the most accurate solar spectral data outdoors.
The MS-711 and MS-712 spectroradiometer are unique all weather concept spectroradiometers with no moving parts and temperature controlled spectrometers. The MS-712 can be used stand alone, but in combination with the MS-711 it covers the spectral range from 300nm to 1700nm. MS-711 measures in the range from 300nm and 1100nm, and MS-712 covers the near-infrared (NIR) range between 900nm and 1700nm. Both spectroradiometers are accurately calibrated with traceability to the International Standards and issued with a calibration uncertainty budget.
Temperature changes of the detector inside the spectrometer have a strong effect on the measurement uncertainity. Therefore the sensor unit inside the MS-711 and MS712 main body is accurately controlled at a stable temperature in order to provide the best performance in a wide operating temperature range. The rugged optical design of the diffusor and input optics make the MS spectroradiometer series concept superior to any fiber optic spectroradiometer which will be susceptibel to mechnical vibration and handling. The MS spectroradiometer series are designed for permanent installation, but are are perfectly suited as a traveling reference.
Both spectroradiometers have a separate power supply and can be controlled through RS232 / 422 by a PC or data logger. The PC software provide different fuctions for operating, data management andvisualisation. Software can also be customized to the individual user purpose by making use of the existing system control functions through the open command protocol.
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 reveals those details. While thermopile pyrheliometer and pyranometer 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.
