For measuring the "irradiance" and "dose" of sterilizing UV light sources!
Short-wavelength, high-energy ultraviolet light in the UV-C spectrum from 100nm to 280nm is widely used for sterilization/disinfection of air, surfaces, and water. To ensure safety from excessive exposure to ultraviolet light while confirming the effectiveness of ultraviolet germicidal irradiation (UVGI), measurements of the sterilization light source and irradiation area are conducted. Gigahertz-Optik offers a wide range of radiometers and spectroradiometers designed and calibrated for the accurate measurement of the irradiance [μW/cm²] and dose [mJ/cm²] of such sterilizing UV light sources. 【Target Light Sources】 - Low-pressure mercury lamp: Wavelength 253.7nm - UV-C LED: Wavelength 265-280nm - Excimer lamp (KrCl): Wavelength 222nm ■ UV Radiometer (Handheld) Ideal for daily measurement of the irradiance of commercially available UVC light sources. It is a low-cost and easy-to-operate measuring instrument. ■ UV Spectroradiometer (Measuring device for spectral irradiance and spectral flux of sterilizing UV) Perfect for research work and product development. It provides the highest radiation accuracy regardless of the type of radiation source. *For more details, please refer to the PDF document or feel free to contact us.
