Davis 6490 UV Radiation Sensor

This precision, patented UV sensor measures the sunburning portion of the UV spectrum. It enables you to display UV index, dose rate, and daily and accumulated dose.

Detects ultraviolet (UV) radiation at wavelengths of 290 to 390 nanometers; the spectral response is closely matched to the Erythema Action Spectrum, defined by McKinlay and Diffey (1987) and internationally recognised as the radiation that is most responsible for causing redness of the human skin.

Compatible with Vantage Pro2 (already included with Vantage Pro2 Plus), Sensor Transmitter, and EnviroMonitor Node.
