The response of the LI200RX sensor to solar radiation is calibrated at LI-COR. If LI-COR repairs the housing, cable, or photodiode, additional repair charges will apply. All factory recalibrations require an RMA (Returned Material Authorization).
The 33476 recalibration service is performed using a reference group of pyranometers traceable to World Radiometric Reference (WRR). This recalibration is ISO 17025 accredited to ASTM E824 standard.
