Ultraviolet Index (UVI)
This meter displays the Ultraviolet Index (UVI) in Normal Display. Below table lists the risk of UVI.
Table UVI risk
UVI | 0-2.9 | 3.0-5.9 | 6.0~7.9 | 8.0~10.9 | 11+ |
Description | Low danger from the sun’s UV rays for the average person | Moderate risk of harm from unprotected sun exposure | High risk of harm from unprotected sun exposure | Very high risk of harm from unprotected sun exposure | Extreme risk of harm from unprotected sun exposure |
