UV index signal lightCollect solar radiation and convert ultraviolet photons within the "sensitive range of the skin" into electrical signals that comply with the World Health Organization and the US EPA UV Index exposure categories. These exposure levels are determined byUV index signal lightThe five colored indicator lights on top represent it. When the signal light is running, it will light up the indicator light corresponding to the level of ultraviolet radiation received by the sensor.
The core component of the signal light is the erythema weighted sensor produced by Solar Light company. For signal light sensors installed indoors, they can be set up remotely, or installed remotely or directly on the signal light for outdoor installation. We can provide hardware for remote installation of sensors, which also includes components for installing signal lights on the wall and indicator poles.
On a clear summer day in the western United States, you can experience a UV index value of up to 10+ In winter, higher index values can also be achieved. That is to say, for a person with Type II skin, they can be burned in 10-15 minutes without taking protective measures. In the northwest of the United States, the UV index value can reach 9+during summer and 3+during winter. These are usually average values.
