Ürün Tanıtımı

The MS-712 can be used stand alone, but is commonly used 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.

The MS-711 and MS-712 spectroradiometer are unique all weather concept spectroradiometers with no moving parts and temperature controlled spectrometers.

Temperature changes of the detector inside the spectrometer have a strong effect on the measurement uncertainty. Therefore the sensor unit inside the MS-711 and MS-712 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 susceptible to mechanical 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 provides different functions for operating, data management and visualization. Software can also be customized to the individual user purpose by making use of the existing system control functions through the open command protocol.

  • Continuous outdoor measurements
  • Instant measurement of full spectrum 900 nm – 1700 nm
  • Excellent Long term stability of detector array
  • Low temperature dependency of detector
  • Fully controllable by PC and datalogger
  • High quality calibration and NIST traceable

Ürün Özellikleri

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 and MS-712 reveal 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.

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.

Main Features

1. All-Weather

MS-711/712 is designed based on our extensive experience in development, production and distribution of various kinds of meteorological instruments. MS-711/712 can be used for continuous outdoor use as all-weather equipment.

2. High Durability

Providing accurate spectral data over a long period of time requires a stable spectrometer and robust opto-mechanical concept. All parts used in the MS-711/712, such as dome, diffuser optics, grating and photo-diode array are designed without any moving parts.

3. Wide Measurement Range

With the automatic exposure function, MS-711/712 can measure a wide range of solar illumination from low to high illuminance in high S/N proportion. MS-711 can measure from 300nm to 1,100nm, MS-712 can measure from 900nm to 1,700nm wavelength range; combination of them will allow taking measurements which covers the wide range of wavelength from 300nm to 1,700nm.

4. Operating Software

The operating software has different measurement functions, to make either a “single measurement” or “scheduled measurement” which takes periodical measurements every day. Data as well as the details of the spectral data can be displayed simultaneously. It combines the data obtained from both MS-711 and MS-712, and takes re-samples and keeps the spectral data in every 1nm and automatically calculates the obtained data.
