When exposed to UVA and UVB wavelengths, the QuantaDose™ test card undergoes a gradual color change from light purple to dark purple directly related to the energy value received.
When exposed to UVC germicidal wavelengths, the QuantaDose™ test card undergoes a rapid color change to a green where fluorescence is directly related to the energy value.
What are Ultra Violet (UV) rays?
UV is an electromagnetic ray wave spectrum from 100 to 400 nm (nanometer). This spectrum can be separated into UV-A, UV-B & UV-C. UV-rays are a part of natural light from the sun.
UV-A and UV-B are already well known for causing suntans, creating vitamin D3 within our bodies, and the unfortunate skin cancers and aging effects after years of sunlight exposure.
Knowledge of UV-C is less spread because these potent shortwave rays normally do not reach us through the protective earth’s ozone “shield.” While UVC light doesn’t make it to the surface of earth naturally, fortunate for our everyday life are its power has been harnessed, and we can instrumentalize UV-C with special light bulbs or deep UV LED’s as the most effective disinfectants without leaving toxic waste chemical detergent residues behind.
UVC light is one of the very best sterilization methods available today. Hence, it is important to ensure your UVC devices are working properly and at the most effective germicidal wavelengths when depending on UV light disinfectant technologies for the safety of your family, friends, and co-workers.
