6-in-1 QUANTADOSE® Multi-Wavelength Bi-Luminescent UVA/UVB/UVC/Far-UVC Light Reusable Professional UV Test Card

The media could not be loaded. This is a great tool that I find to be an absolute must for testing all kinds of glasses worn outdoors to ensure they protect my eyes from damaging UVA and UVB rays. It is very easy to use, and the maker has a detailed explanation page on their website; see the QR code on the back of the card (and in one of my photos). While it also tests for UVC to test the veracity of sanitizing equipment, I got it primarily to test glasses along with a blacklight.I did a little research and spoke to the creator and owner of QuantaDose UV detection cards, and also read up on “Protecting your eyes from the sun’s UV light” published 7/5/22 by the US government’s National Rye Institute (NEI) on the National Health of Health’s (NIH) .gov website. According to this article, UVA and UVB can be damaging to the eyes and the article states, “Look for lenses that provide 99 to 100 percent protection from UVA and UVB or marked as having a UV400 rating.” In testing glasses, I have learned labels cannot always be trusted and sometimes it can be in the user’s favor (and in some cases there is no label at all). I did a video (1m 45s) testing these sunglasses and other glasses regarding UV protection with the QuantaDose card and a 365nm blacklight.VIDEO – My short (1m 45s) attached video shows the following:(Note I wore UV400 glasses while using the blacklight for this testing video.)1 - The front and back of the card and 365nm blacklight2 - Showing how the card turns violet when exposed to longwave UVA and UVB light3 - Testing a pair of clear safety glasses that DO protect against UVA and UVB light4 - Mislabeled glasses that do NOT protect from blue or UVA and UVB light5 – Tests on all 3 pair of these sunglasses; they DO appear to protect against UVA and UVB lightGiven what I learned about eye health and UV light, I will be testing all of our sunglasses, work glasses, etc., for UVA and UVB protection for wearing outside (even on cloudy days), and all indoor reading and other glasses for blue light protection (using a blue light and a blue light detection card) …the 365nm blacklight I got and this UV detection card to me are a necessary and great investments.The credit card sized card is made of nice quality plastic and is the 3rd iteration (and most versatile) of QuantaDose’s UV cards. To me it worth far more than the $10.99 US price at the time I purchased it and is earns a well-deserved 5 (plus) stars in my book.

I purchased this to check my medical grade UVC sanitizer box. When the UVC didn't show after testing it in the sanitizer box I called the number on the back of the Quantadose card. The person I spoke to was a wealth of information. He explained how the card works and how to test for UVC. He said the UVC indicator disappears as soon as the sanitizer is open. He encouraged caution and protection and said I could place the card inside of the sanitizer with my phone on video record.I was able to verify UVC up to 254nm. The Quantadose representative was professional, educational and truthfully so nice. He said to call back anytime if I had more questions or needed help.

I don't have any other equipment or knowledge to back it up, but seems to be legit. Bought to check if UV-C bulbs for air sanitizers I bought here on amazon also were fake (they weren't, according to this). They react to the UV bulbs, but not other lights.

I’m using the card to measure UV in a plant growing cabinet. The different UV lights I have are both reptile UV bulbs which report a UVA a percentages of 30% and UVB percentages of 5% and 15%. The card does a fine job indicating that UV is present but differentiating the color change on the card to determine intensity is not easy since it resets quickly when taken away from the light source and has to be held at relatively close range to see higher detection levels. Still a good purchase to make sure the bulbs you are getting are providing at least some of the UV advertised.

I haven't played with this too much yet. Was a purchase of curiosity and potential, not of a need. Its about the side of playing card. It comes in a nice black plastic pouch. Not sure yet if what we see is a REACTION on the surface of the material, or if it's just a clever way of allowing our eyes to perceive the existence of the rays through pigment interactions and reflection of light. Like that if shifts the frequency in a way that creates a visible artifact. Not sure yet. But it works. In direct sunlight, and dark it was as described. For now I keep it in the plastic pouch. But if the card does react directly and needs darkness to restore I might like to keep it in an insulated felt bag instead.In terms of cost to value ratio, I think this was well worth it. Just cheep enough to entice me to make the purchase and test it out.

This doesn't register a 55W UV-A HVAC sterilization bulb from 12" away. So it's frustratingly not sensitive enough to just place somewhere in the serilization container to test the bulb. It must be placed right next to the bulb to register the slightest amount of change.Maybe it's only for medical-grade sterilization devices? Or maybe my bulb is defective and this meter is showing that its radiation level isn't effective?The 2nd Gen QuantaDose card also sold here is more sensitive (at least 2x more).But both of them fade rapidly. It's half-life appears to be 2-3s.After 5 minutes of exposure, it fades completely within 5 seconds!As UV radiation is dangerous, I thought it best to close this card off in the enclusre with the bulb. But that makes it difficult to get it open in time to read it. So even leaving the enclosure open shows that this card is difficult to get to even begin to glow purple.I prefer the 2nd Gen QuantaDose, since it's slightly more sensitive to UV: https://www.amazon.com/dp/B08KZZ54BZ
