Davis Instruments Solar Radiation Sensor - 6450

Measures solar radiation and is required (along with an anemometer and a temperature/humidity sensor) if you wish to monitor evapotranspiration.

Features:

• Diffuser element and housing are carefully designed for accurate cosine response
• Silicon photo diode provides good match to solar spectrum
• Two-piece housing minimizes radiation heating, allows convection cooling of the sensor, and prevents the trapping of water or dust
• Includes built-in level and 2' (0.6 m) cable
• Compatible with both original Vantage Pro and Vantage Pro2. You may also need a UV Sensor (#6490) and Sensor Mounting Shelf (#6673)
