SR15-D2A2 Digital First Class Pyranometer Describe： User's Manual Datasheet

SR15-D2A2 Digital First Class Pyranometer

Calibration of SR15 pyranometer has been improved; our latest calibration method results in an uncertainty of the sensitivity of 1.8 %, compared to typical uncertainties of higher than 2.8 % for this pyranometer class. SR15’s response time is < 10 s, a significant improvement relative to earlier sensors and competitors.

Use as Sunshine Duration Sensor

WMO has approved the “pyranometric method” to calculate sunshine duration from pyranometer measurements in WMO-No. 8, Guide to Meteorological Instruments and Methods of Observation. This implies that SR15 may be used, in combination with appropriate software, to estimate sunshine duration. This is much more cost-effective than using a dedicated sunshine duration sensor. Ask for our application note.
