Global radiation

  • EMS 11 (diode)
    It should not be used for the measurement of reflected or transmitted radiation. The spectral characteristics does not cover the whole range of sunlight.
  • LP02 (thermal)
    Thermal principle. “Real pyranometer”.

Photosynthetic active radiation

  • EMS 12 
    The sensor has glass diffuser. It doesn’t require frequent recalibration.
  • Apogee SQ-110
    Economy solution.

Net radiation
