MS-711N DNI Spectroradiometer

SKU: N/A Categories: ,

Direct-normal UV–Visible–NIR spectroradiometer for precision 300–1100 nm solar spectrum measurement, featuring an integrated 5° collimating tube, heated quartz window and temperature-controlled detector.

Typical Applications

  • Direct Normal Irradiance spectral measurement
  • Photovoltaic research
  • CPV performance analysis
  • Solar resource assessment
  • Atmospheric spectral research
  • Aerosol and atmospheric studies
  • Solar-cell spectral response analysis
  • Sun-tracker monitoring stations
  • Reference solar spectral measurements
  • Permanent outdoor research installations

The MS-711N DNI Spectroradiometer is an all-weather direct normal spectral irradiance sensor designed to measure the direct solar spectrum from 300 to 1100 nm. Based on EKO’s new-generation grating spectroradiometer platform, the instrument combines a temperature-controlled detector, optical resolution below 7 nm and NIST-traceable calibration with an integrated 5° collimating tube, quartz window and window heater. Mounted on a compatible EKO sun tracker, the MS-711N DNI follows the solar disc automatically to provide wavelength-resolved Direct Normal Irradiance (DNI) data for photovoltaic, CPV, atmospheric and solar-resource research.

Key Features

  • Direct normal spectral irradiance measurement
  • 300–1100 nm UV–Visible–NIR range
  • Integrated fixed collimating tube
  • 5° field of view
  • Quartz collimator window
  • Integrated window heater
  • Optical resolution below 7 nm
  • ±0.2 nm wavelength accuracy
  • Temperature-controlled detector core
  • Automatic 10–5000 ms exposure
  • NIST-traceable calibration
  • Calibration uncertainty budget
  • RS-422 / RS-232 communication
  • IP65 environmental protection
  • Sun-tracker mounting capability

Unlike the standard MS-711N, the DNI version physically limits its field of view to 5° around the solar disc, allowing the instrument to isolate the direct-beam spectrum when continuously aligned to the sun by a tracker.
