What is a UV meter?

ultraviolet (UV) light is radiation invisible to the human eye that can be harmful or beneficial depending on concentration and use. UV meter can detect ultraviolet light on a wide range of sensitivity. UV meters can be purchased from many sources, including outdoor suppliers, scientific products and many online traders.

The sun is a large natural source of UV light that can be dangerous to people to expose themselves in a certain amount. Repetition and sunscreen are relatively effective defense against UV light, but the UV meter can also be useful for those who spend time in a large outside. These simple meters allow users to know the level of UV rays and what type of protection it might be necessary. For those who have the skin very sensitive, the UV meter can clearly indicate what level of sunscreen to use and how long it is safe to stay in full sunlight.

Museum holding historical works of art often uses UV monitor to measurepotential damage caused by invaluable work. Like ultraviolet rays, they burn the skin, they can also damage parchment, canvas, colors and other art -related materials over time. In the most famous museums, paintings and other pieces can be placed specifically in areas that protect them from most UV lights, as determined by a UV meter. In some museums and collections, ultraviolet values ​​are regularly carried out to ensure that the levels have not changed and do not reach dangerous heights.

UV meter is usually a small, pocket device that creates a digital reading based on data taken through sensors. Some may include wizards that show where the UVS level falls on a scale, or to provide recommendations based on reading on exposure time. UV meter created for home or outdoor use will usually be able to feel UV light from the sun rather than from the artificial source of the black lights.

ultraviolet light has many uses including sterilizator. Water and food are sometimes cleaned using ultraviolet germicidal irradiation, which uses focused UV light to destroy and sterilize microorganisms. It is also often used to sterilize medical tools and equipment, even sometimes as an air cleaner. To ensure that the UV sterilizer works properly, operators use a highly sensitive UV meter to detect whether the emitted beams are at an acceptable level for sterilization.
