The QuantaDose Multi-Wavelength Bi-Luminescent UVA/UVB/UVC/Far-UV Test Card has functionality on both sides. On the one side, you have five tests: 1st a UVC indicator Test, 2nd a Wideband UV Intensity Test, 3rd a Shortwave Test, and 4th a Longwave UV Test, which is designed to indicate whether a UV bulb or UV light is indeed irradiating the type of UV light as claimed, most important is the 5th test that confirms >300 microwatts at 254nm UVC when the letters UV remain visible in the inner circle after the card is removed from a UVC light source. On the other side, in the 6th test, you can test any UVC or Far UVC bulb’s beam angle with a large surface area of the test card covered in a luminescent shortwave analyte sensitive only to UVGI wavelengths. We wanted to create a self-powered simple-to-use test card that was a multi-tool for UV light detection. Over two years of R&D went into this card so that it would do what no other test card ever designed could do. Reusability when detecting UV spectrum between Longwave UV, Shortwave UV, UVGI UVC, UVC Intensity conformation, and UV intensity scale all in one easy-to-use test card.

Great item to have on hand to check your u. V, it should be a must yet you own one

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.That's why I prefer the 2nd Gen QuantaDose at this time: https://www.amazon.com/dp/B08KZZ54BZ

Used this to ensure UVC disinfecting light was operating within the promised specs. Works perfectly and is easy to read.

Used it to check the UV-protective film that I had installed on some windows of mine. Found that some came through, but not much. Or to be precise, some UV-C did get through, but the UV-C in sunlight is negligible already.

I was looking for an inexpensive way to compare the effectiveness of low cost UVC sterilization products and this is it! It’s quick to use and quickly verifies whether a product generates UVC energy in the 254nm wavelength necessary to destroy bacteria and neutralize viruses. But just be aware that the phosphors used will degrade with extensive usage so keep the card in its black light proof cover when not in use. The photo shows the basic card when not being exposed, then the 2nd photo shows the card exposed by a UVC Sterilization wand at about 3 inches. Notice that the top left has the prominent UV-C glowing, which indicates the energy is in the UVC band. Then after removing the light source, if the UV in the middle circle is still visible due to the purple color surrounding it, you know that the source had an intensity greater than 300 μW/cm², which is necessary for complete sterilization when a surface is exposed for at least 5s.

Seems simple enough—pull out the card and let light shine on it, but without going to the website and scrolling through the sample images, a person that only occasionally uses the card (probably most people) won't know how to interpret the findings. Even with going to the website, there are still too many unanswered questions.It would be nice to have the sample images from the website printed on the back along with the existing QR code for more details. Even better would be to also add explanatory text on the front. For instance, what do the different shades of purple and green mean—intensity?—strongest wavelength? And when they appear in the outer ring, is that good or bad? Are there numerical values associated with the shades or rings, and if so, why are they not printed somewhere? And in the middle section, there is a key for shortwave/longwave with shades of gray. Where do those shades of gray appear?—is one the text color and the other the background?—does it only show one or the other shortwave/longwave at a time?—which one takes priority if both wavelengths are present?
