Instructions for Use
  • To use, peel off the protective strip to expose the adhesive and place the dosimeter 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 disinfection cycle is complete, the color-change allows you to see if you’ve reached 25, 50 to 100 mJ/cm².
  • UVC Dosimeters are intended for one-use-only and should not be reused. Store at room temperature and away from direct sunlight.

Patented photochromatic ink changes color to indicate the level of UV-C irradiation achieved on surfaces


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. Click to read.


Recommended for use with UV-C disinfection systems utilizing 260-280 nm wavelengths


Great for in-servicing, staff training, validating UV-C lamp performance, and determining optimal lamp run-times for efficiency.
