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' (0.6M) cable.Compatible with both original Vantage Pro and Vantage Pro2.You may also need a UV Sensor (#6490) and Sensor Mounting Shelf (#6673).
