What is a UVC Test Card?The “Original” UVC Test Card is a simple, at-home “DOSIMETER” test anyone can use to “PROVE” their UVC wand, light, lamp, box, bag, or sanitizer IS ACTUALLY KILLING VIRUSES. HOW DOES IT WORK? If your UVC device is the real deal, it will “Tan” the Dosimeter card when, and only when, your device has reached the Germicidal level capable of killing viruses, and not before. Once the Dosimeter card has proven your device will actually kill viruses, it will not change back to it’s original color. If your card has not changed color during your test, the card is either too far away from the light or not exposed long enough -or- it’s not being exposed to a genuine UVC germicidal light. If your device is fake, your card can be used again and again until you finally test a Real Germicidal light that produces pure germicidal protection. For nearly 10 years now and Hospitals and Labs are still using our Dosimeter cards. Why? With experience, comes wisdom. They know a “Dosimeter” card proves a UVC light is, or isn’t producing germicidal protection. They understand that not all UVC lights are the same. There are UVC lights that aren’t powerful enough to kill viruses and some degrade over time and slowly lose the ability to kill viruses. Hospitals and labs rely on the best card to get the job done. They can’t simply rely on a re-usable card that simply “glows” telling them them a UVC light is a UVC light. They need to know if their UVC germicidal light IS AND ISN’T functioning good enough to kill viruses. They test it on day 1, and many days forward. ALWAYS – “TEST IT BEFORE YOU TRUST IT!” Beware of the re-usable UVC Test Card that “glows” in UVC light. It’s not a UVC “germicidal” test. It’s nothing more than a simple UVC “Light” Test. It does not distinguish between low power UVC and high power UVC. Low power UVC can take hours to kill and high power can easily kill viruses in a few seconds. Many low voltage UVC gadgets, like my Grandma’s clearly labeled “UVC” wand was tested by a Dosimeter. It actually took about an hour before it begin killing anything and she didn’t know because she trusted a clearly labeled “UVC” Wand and the glow of a reusable test card. Yes it’s UVC and yes the re-usable test card glowed even though it was not killing anything, the way she used it. And this scares me because a re-usable test card “glowed” making my Grandma believe that her UVC device can kill viruses if she waives it over her phone. And it can’t! Just makes me wonder how many other people did it give a “FALSE” feeling of safety. Bottom line. Buy a UVC Test Card with Dosimeter Technology and test it. For nearly 10 years it’s still providing “PROOF” to hospitals and labs that their UVC devices can (or can’t) kill viruses. The Dosimeter is the only that can prove a UVC Device will kill nasty viruses. Let’s face it, we don’t need proof our UVC gadgets have a UVC light. We want to know that it can and will kill viruses and keep our family safe. There’s a big difference and the UVC Dosimeter is the only one that can do that.
