Description

In direct sunlight, sunburn can start in as little as ten minutes. With the Davis UV Sensor, you can measure the sunburning portion of the UV spectrum and calculate UV index, dose rate, and daily and accumulated dose. (This sensor is included with the Vantage Pro and Pro2 Plus models.)

The multi-layer filter provides a spectral response that closely matches the Erythema Action Spectrum. This curve illustrates the effectiveness of different wavelengths of ultraviolet (UV) radiation in causing erythema (sunburn) in human skin. The two-piece housing minimizes radiation heating and allows sensor convection cooling, preventing water or dust infiltration.

Features:

Sensor includes a built-in level
Two feet of cable included
Compatible with both the original Vantage Pro and Vantage Pro2
