UV Sensor
Product Number：Davis 6490
● Measures the sunburning portion of the UV spectrum. Allows you to display UV index, dose rate, and daily and accumulated dose.
● Diffuser provides excellent cosine response.
● Measures global solar UV irradiance, which includes both directly transmitted and scattered UV.
● Transducer responds only to radiation in the region of interest and is stable in the presence of heat and humidity.
● Cutoff ring with a comb structure for cosine response of ± 4% FS.
● Two-piece housing minimizes radiation heating, allows convection cooling of the sensor, and prevents the trapping of water or dust.

Davis 6490 UV Sensor
Measures the intensity of the sunburning portion of the UV spectrum (UVA and UVB), closely matching the Erythema Action Spectrum. Allows you to display UV index, dose rate, and daily and accumulated dose. Latest technology transducer and newly designed electronics provide greater accuracy and stability. The comb structure provides improved cosine response accuracy at zenith angles up to 90 degrees. Two-piece housing minimizes radiation heating, allows convective cooling of the sensor, and prevents the trapping of water or dust. To mount next to a Rain Collector, use the Sensor Mounting Shelf. Use the Universal Mounting Bracket for other applications. Includes 2 ft. (0,6 m) cable.
