For 222 Devices

UVC 222 Dots 

Introducing the first-ever UVC Dosimeter for Far UV-C

Using a patented, UV-sensitive material, UVC222-Dots react to UV-C at 222 nm. These color-changing adhesive indicators are ideal for use with Far 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.
