LI-COR LI-200R [LI-200R-BL-50] Solar Radiation Sensor w/ Microamp Output, 50m Cable and Bare Leads

For The LI‑200R measures total solar radiation with an unfiltered silicon photodiode. Although the LI‑200R does not measure the total solar spectrum, its measurements correspond closely to first-class thermopiles under outdoor conditions.

The crown of the sensor rapidly sheds water, reducing pooling around the sensor. It also physically blocks light that is outside the hemisphere of sensitivity, providing precise cosine response.

Ideal for agricultural, meteorological, solar energy, and environmental research, it is available with a variety of cable lengths and output signals for compatibility with most data loggers.
