    254 TRI Check

    UVC 254 TRI Check provide visible evidence of successful germicidal irradiation.

    Using a patented, photochromic ink, TRI Check dosimeters react to UV-C at 254 nm. 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.
