Transmitters with inputs for solar radiance (pyranometer)

GS41Acf The GS41Acf provides one physical pyranometer input and two calculated channels.
  • The physical input is for use with the Skye SKS1110 or Kipp and Zonen CMP3 pyranometer.
  • The calculated channels are average value (5 minute rolling average with 30 second period) and cumulative value (i.e. to give Watt hours rather than Watts).
  • The Pyranometer must be ordered separately.
OD-41A Weatherproof (IP65 rated) polycarbonate enclosure with transmitter, primarily intended for wall mounting.
  • Supplied with a GS41Acf installed.
  • The transmitter can be installed together with an additional battery pack (type SP1118) for more than 2 years operation (or where very fast data logging is a requirement).
  • The enclosure is provided with 4 fixing holes that are obscured when the cover is fitted.
  • The pyranometer must be ordered separately.
