For 254 Devices

UVC 254 Dots 

254 Dots provide visible evidence of successful germicidal irradiation from UV-C devices producing 254 nm wavelengths.

UVC Dosimeters are proven to color-indicate doses of 25, 50, 75 and 100 mJ/cm² that have been delivered from devices producing 254 nm. UVC Dosimeters are an important and necessary tool to validate ultraviolet output so you can visibly see if sufficient irradiation has been delivered to inactivate harmful pathogens.

Currently available as 1″ dots. 5-dot card coming soon!
