HQRP UV Chain UV Meter/Meter/Detector/Indicator ; Ultraviolet Sunlight Meter

The center of the Solar UV Meter with 3D effect can change series of color according to Solar UV Index. It is how Solar UV measuring function is maintained. The 4 standard color indicators show intensity of Solar UV rays. To know the Solar UV Index, it is enough to compare the colorchange with the 4 standard colors around. The greater intensivity is the darker is the color.Clear colors mean small intensity and dark colors mean great intensivity of Solar UV rays. Very light purple: low intensity, UV index 1-2. Sun-protection not necessary. Light purple: medium intensity, UV y strong intensity, UV index 8-11. Avoid exposure. Circle-shaped UV tester with chain is convenient to use.
