    UVC 254 TRI Card 12-Packs 

    Our most popular TRI Cards are now available in packs of 12!

    254 TRI Cards provide visible evidence of successful germicidal irradiation from UV-C devices using the 254 nm wavelength. They provide a simple, accurate way to see how much germicidal UV-C has been delivered to surfaces around a room or to objects inside a disinfection cabinet. Color-changing UVC Dosimeters help you validate any UV-C device and provide real-time visible evidence of successful UVGI.
