CMP3 Pyranometer
5
Features:
•
Includes a white snap-on sun shield that reduces the sensor's
temperature
•
Provides measurements in direct sunlight, under plant canopies, when
the sky is cloudy, and in artificial light
•
Measures reflected solar radiation when inverted
•
Includes bubble level and level
l
ing screws eliminating need for a
separate leve
l
ling base, which simplifies installation
•
Acceptable for providing the solar radiation data used in stability
estimations
•
Compatible with Campbell Scientific CRBasic data loggers: CR6,
CR3000, CR1000X, CR800-series, CR300-series, CR1000
