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.

To purchase in the US and Canada, please visit our distributor, American Ultraviolet.

    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 irradiation on a surface. Especially useful in shadowed areas


    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*


    Validated by leading researchers in the U.S., U.K. and Sweden and trusted by UV-C manufacturers throughout the world


    Recommended for use with UV-C disinfection systems in healthcare facilities, physician and dental practices, commercial spaces and more


    Great for in-servicing, training, validating UV-C lamp performance, and as a simple reporting tool for Infection Control and Environmental Services

    uvc 100 product family dosimeters

    UVC 100 Dosimeters are available in two easy-to-use formats:

    • 2.5” x 3.5” cards
    • 1” dots

    Both formats have an adhesive backing and can be applied to surfaces and/or equipment that will be disinfected with UV-C irradiation. The yellow center on the card (or the entire dot) will change color with UVC exposure, indicating up to 100 mJ/cm². The color-changes associated with the UVC 100 can be correlated to a dose necessary to achieve a 3-log (99.9%) reduction of MRSA and C. Diff.


    Instructions for use

    To use, peel off the protective strip to expose the adhesive and place UVC 100 Dosimeters on or adjacent to any equipment or surface that will be disinfected with ultraviolet germicidal irradiation. Make sure the yellow indicator area faces toward the UV-C light source. After the UV-C disinfection cycle is complete, confirm the color change on the cards or dots within 24 hours. UVC 100 Dosimeters are intended for one-use-only and should not be reused.
