SR05 pyranometer series

Second class pyranometers with various outputs

Back to overview

SR05 pyranometer ball levelling

SR05 series is the most affordable range of pyranometers meeting ISO 9060 second class requirements. SR05 measures solar radiation received by a plane surface, in W/m2, from a 180 o field of view angle. It is ideal for general solar radiation measurements in (agro-)meteorological networks and PV monitoring. The pyranometer is easy to mount and install, in particular with SR05's ball levelling mechanism. Various outputs are available, both digital and analogue, for ease of integration.

SR05 benefits

  • Industry standard digital outputs: easy implementation and servicing
  • Easy mounting and levelling
  • Pricing: second class pyranometers finally affordable for large networks

Design and output

SR05 pyranometer employs a thermopile sensor with black coated surface, one dome and an anodised aluminium body with visible bubble level. SR05 has a variety of industry standard outputs, both digital and analogue:

  • SR05-D1A3: digital sensor with Modbus over RS-485 and analogue 0-1 V output
  • SR05-D2A2: digital sensor with Modbus over TTL and analogue 4–20 mA output
  • SR05-A1: analogue sensor with analogue millivolt output

SR05 pyranometer mounting and levelling

Optionally SR05 has a unique ball levelling mechanism and tube mount for easy mounting and levelling on a (non-)horizontal surface or tube. Click the Gallery tab to view some examples.

Suggested use

  • general solar radiation measurements
  • (agro-)meteorological networks
  • PV power plant monitoring

Sensor Manager

For communication between a PC and the digital versions of model SR05, the Hukseflux Sensor Manager software is downloadable. It allows the user to plot and export data, and change the SR05 Modbus address and its communication settings.


  • longer cable lengths (10, 20 metres)
  • extension cable with connector pair (10, 20 metres)
  • with ball levelling
  • with ball levelling and tube mount (for tube diameters 25 to 40 mm)
  • OEM versions

Please take a look at the SR05 series product brochure and user manual (SR05-D1A3 and SR05-D2A2) via the download buttons. SR05-A1, the analogue version of model SR05, has a seperate manual, which can be downloaded here.
