Germicidal UVC Quick Check Dosimeter Card | Registers Visual Check Mark at UVC Exposure Dose of 6mJ/cm² at 254 nm

Germicidal UVC light is an effective tool for eliminating pathogens on surfaces, but how do you quickly and clearly show that UVC energy has disinfected a surface? These Quick Check dosimeter cards can be placed on any surface to monitor any exposure to UVC energy. The color on the card changes as it is exposed to UVC energy, and a visual check mark displays when the card has received enough energy to reach a dose of 6mJ/cm².

These Quick Check UVC cards are a great tool for showing that a space or surface has been disinfected, commissioning UVC fixtures, and checking the output of UVC fixtures over time.

The technology consists of a photo-chromatic ink that changes color when it is stimulated by certain UVC radiation (253.7 nanometers). The cards are not an accurate measurement for 222nm Far-UVC, pulsed xenon UVC, or LED UVC light sources.

Quick Check Dosimeter Card Overview: 

Limitations of the Quick Check UVC Dosimeter Card:

• Designed for single, daily use
• Do not use outdoors and do not expose to direct sunlight
• Discard after each use — do not reuse
• Designed only for UVC devices emitting 254 nm energy (not for use with LED, far-UVC, or pulsed xenon light sources)
