Germicidal UV Light (UV Disinfection) Measurement
ILT offers germicidal radiometer systems for testing effective germicidal ultraviolet irradiance for most short wave UV sources including ozone producing and non-ozone producing, low and medium pressure mercury lamps. ILT sensors come in three configurations - narrow band (line) 254 nm, effective germicidal UV light measurements conforming to the IES Luckiesh and DIN standards, and unfiltered sensors calibrated at at 254 nm for testing low pressure mercury lamps where 95% of the output is at 254 nm.

Use of ultraviolet light for germicidal UV light disinfection is a technology which can be applied to air, water and surfaces. Ultraviolet Germicidal Irradiance (UVGI) rapidly replacing traditional disinfection methodsGermicidal disinfection by exposure to ultraviolet (UV) light is seeing rapid deployment in food, pharmaceutical, hospitality, and medical markets throughout the world due to the effectiveness, ease of use, adaptability and relatively low expense of the technology as compared with the more complex, time consuming and costly methods currently in use such as chemical, steam, or heat disinfection. |

Low pressure mercury lamps - most cost-effective germicidal UV light sourceUV irradiation kills a broad range of microbes, in essence breaking the molecular bonds that hold the organism’s DNA together. The most effective wavelength for accomplishing this is 263 nanometers (nm). However, due to the more readily available and moderately effective output at 254 nm produced by inexpensive low pressure Mercury (Hg) lamps, 254 nm has become the generally accepted action wavelength and low pressure Hg lamps the most utilized in low to medium intensity germicidal applications such as food processing, low volume water treatment, and medical service and manufacturing. The broader spectral output and greater intensity from medium pressure UV lamps means they will continue to be utilized in applications requiring high intensity germicidal UV exposure where the large numbers of low pressure Hg lamps required to meet the intensity levels would be impractical due to cost and space, such as in large volume municipal water treatment facilities. |
