MS-720 portable spectroradiometer measures spectral irradiance from 350-1050nm Visible to Near-Infrared radiation. It calculates, displays and saves measurements of Irradiance (W/m2), illuminance (lux) and PPFD (µmol/m2/s).

The MS-720 is mainly used for spectral data acquisition of solar radiation, geological features, vegetation, oceanography, remote sensing and many other field-based applications.

Analytik delivers solar radiation spectroradiometers to the UK and Ireland from EKO Instruments.

We will be happy to work together with you on a solution with the full support of the EKO Instruments team, based in The Netherlands. Visit our contact page, request a quote, or call us on +44 (0)1954 232 776.



MS-720 is a rugged and lightweight handheld spectral sensor with an integrated LCD screen and internal memory, suitable for outdoor solar radiation and internal greenhouse spectral measurements. At its heart lies a Zeiss diffraction grating spectrometer with sensitive integrated photo-diode array.

Data files are downloaded to a PC or laptop using the free MS-720 control software. Several scientific functions are incorporated (e.g calculate the integrated irradiance of a measured spectrum against a reference spectrum).

Key Features:

  • Automatically displays Irradiance (W/m2), illuminance (lux) and PPFD (µmol/m2/s)
  • Small, light and portable (W100 x D160 x H60mm, 720g).
  • Operation is simple with the integrated LCD and tactile switches.
  • A cosine correcting diffuser, Zeiss grating spectrometer and temperature-corrected diode-array are its key components.
  • Highly reliable because there are no moving parts that could affect measurement accuracy.
  • Integrated software automatically determines the optimal exposure period to get the best spectral measurement.
