UVC Intensity Stickers - Testing

As we are working with the US Food and Drug Administration, the FDA, on the analysis of the UVC Decontamination Chamber (UVC-DC) we keep learning more and more. They, the team at the FDA, recommended we do some testing inside of the UVC-DC with color changing UV stickers. These stickers are called UVC Intensity Strips or “Stickers”. We conducted our first several experiments this past week with those stickers and it was really interesting to see the color change as the UV dosage increased. The good news is that the stickers change color, fairly consistently, at different positions throughout the chamber, which shows us that the UV light is being distributed throughout the chamber.

The photos below show the sticker as yellow, before UV, and then dark green, after the UV exposure time. The image of the chart shows the progression as the UV dosage (time in the chamber) increases. That cool looking blue photo is looking into the chamber via the view window. Take care. David

About the UVC Decontamination Chamber (UVC-DC):

The UVC Decontamination Chamber is a Portable On-Site Face Mask Disinfection Chamber for disposable face masks. The disinfection method is eight (8) germicidal UV-C bulbs positioned in front of and behind the N95 face masks. 10 face masks can be disinfected during each 15-minute cycle. The UVC-DC can be used at hospitals, fire stations, police stations, nursing homes, etc., and can be located near the actual point of use. One or more UVC-DC's can be located at each station, department, wing, hallway or emergency room, so there is no need to handle and disinfect mass numbers of masks at a central or off-site location. The UVC-DC is simple to operate, easy to roll around, and versatile enough to be transported in the back of a minivan or SUV.
