DIGITAL UV RADIOMETER

Standard UVB meters measure total UVB rays and are useful for seeing if a lamp emits UVB, as well as seeing the decay in UVB over a period of time. Readings from standard UVB meters can be confusing and misleading, especially when trying to make comparisons between levels of natural light and UVB lamps. Developed by the World Health Organization, the UV index is a measure of ultraviolet radiation from sunlight which contributes to the synthesis of vitamin D, and causes damage to the skin and eyes. It is not simply a measure of total UVB, but instead measures only the specific UVB (and some UVA wavelengths) that are responsible for the aforementioned biological processes. Not all UVB waves are equal in their ability to promote vitamin D synthesis. The UV Index is often given in weather reports and uses a color-coded scale to indicate the intensity of the UV rays.- To det
