UVC100-MCD has two color references for MRSA and C-diff (correlated to 50 and 100 mJ/cm²)

UVC 100 Dosimeters are designed to visually indicate an accumulated dose of UV-C ranging from 25, 50, 75 and 100 mJ/cm².

Using a patented, UV-sensitive material, UVC 100 Dosimeters react to UV-C at 254 nm, the peak wavelength for germicidal effectiveness. These color-changing indicators are ideal for use with UV-C disinfection systems and help you validate your devices, procedures and visibly see if target surfaces have received enough germicidal irradiation to kill  harmful bacteria, viruses and spores.

• Patented photochromatic ink changes color to indicate the level of UV-C irradiation on surfaces (254 nm)
• Visibly demonstrates the accumulated dose of UV-C so you can confirm that a surface has received an optimal level of germicidal irradiation. A recent study indicates that SARS-CoV-2 can be inactivated by a dose of 22 mJ/cm².
• When exposed to an appropriate dose of UV-C, the yellow area changes to orange and deep pink, which can be correlated to a 3-log reduction of MRSA and C.Diff, based on 50 and 100 mJ/cm² respectively
• Validated by leading researchers in the U.S., U.K. and Sweden and trusted by UV-C manufacturers throughout the world. UVC Dosimeter by Intellego have been used in multiple US research studies to confirm UV-C effectiveness.
• Recommended for use with UV-C disinfection systems in healthcare facilities, physician and dental practices, commercial spaces and more
• Great for in-servicing, staff training, validating UV-C lamp performance, and as a simple reporting tool for Infection Control and Environmental Services
