LONG-TERM TEST RESULTS
The Utah State University Crop Physiology Lab has
conducted a long-term outdoor pyranometer study for the past
10 years.
Their results are available below and show that the Apogee
pyranometers compare well to other silicon-cell and
thermopile pyranometers. Each model is compared to a heated
and ventilated Kipp and Zonen CM21 thermopile pyranometer.
