Quantadose UVC Light Test Card with UVC Light Wavelength Indicator and Intensity Test
The QuantaDose dual wavelength multi-strip UVC test card measures UV intensity with a very specialized analyte for wide-band photochromic UV dosimetry combined with a narrow-band short-wave fluorescent indicator for testing optimal UVC germicidal wavelengths. QuantaDose provides you with real-time results for super fast verification/validation purposes to avoid an increasing number of fake and defective germicidal UVC light products on the market today.
QuantaDose UVC test cards are a basic, reliable, low cost, simple, in-house, and right out of your pocket method of monitoring UV intensity along with verifying that the optimal UVC germicidal light wavelengths are being used in your disinfection process without spending hundreds of dollars on fragile UV and UVC light meters.
What is QuantaDose?
We are Quanta X Technology, the manufacture of QuantaDose UVC Test Cards, is an American company founded during the start of the pandemic in 2020 by people who have spent their entire lives in the research and development of technologies that utilize electromagnetic radiation. Today they have focused their talents on the transmission and detection of UVC light from consumer-engineered UVC devices by manufacturing rapid ultraviolet-type C analytical test instruments.
Top and Bottom Light Sensor Test Wavelength of UV Exposure by QuantaDose
Basic, Reliable, Low Cost, Simple Method of Monitoring UV Intensity
The letters UV-C glow brightly when measuring the correct UVGI wavelengths for a minimum calibrated reference point of 300 µW/cm² UVC intensity through simultaneous word legibility and letter visibility. The1st Edition dual-wavelength UVC test card measures UV intensity with a very specialized analyte for wide-band photochromic UV intensity dosage between 250-400 nm combined with a narrow-band short-wave fluorescent UVGI indicator for testing optimal UVC germicidal wavelengths.
- Package Dimension: 3.5" x 2.5" x 0.1"
- Instant On/Off Fluorescent UVC Indicator: 222 -280 nm
- Wide-band UV Between 200-400nm UVA/UVB/UVC
Methods to Verify a UVC Product's Claims of Germicidal Wavelengths and Germicidal Intensity.
QuantaDose has created a specially formulated ink chemistry that is sensitive to only optimal germicidal UVC which will not fluoresce to visible light or UVA and UVB. This ensures only germicidal wavelengths between 250-270nm are shown in bright green.
Bottom Light Sensor Test Intensity of UV Exposure: When exposed to UVA, UVB & UVC wavelengths, the QuantaDose test card undergoes a gradual color change in seconds from clear to light purple, displaying the word "ULTRAVIOLET " at approximately 300 µW/cm² UVC where color is directly related to the energy value received. Temporary photochromic dosimeter color is used to check intensity after exposure and should be checked immediately after exposure for most accurate intensity results. Test is completed in 15 secs, remove card from source!

I have a retina problem and need to avoid UV rays. I went to three optical stores trying to get my sunglasses tested. None had a device to do it. Then I found this inexpensive card on Amazon. It does the job, giving an idea of the degree of protection. I also checked my families sunglasses. Nice product!

I bought this card to test some sunglasses I have because I wasn't sure if they had any UV protection. It's so simple to use and it put my mind at ease.

This thing really works! I used it to verify a UVB flashlight was blocked by UVB-resistant eyeglasses. I didn't test the UVC function. Strongly recommended when dealing with harmful UV light.

Worked perfectly. Only criticism is the reactive "bar" is slightly small.I used it to test some shirts from amazon that claimed to be UPF 50+. The card worked -- the shirts did not! Card showed shirts let through LOTs of UV light.(My polarized sunglasses let through zero as a test.)Also showed how UV is still a danger on cloudy days -- although lesser than direct sun.Buy this card, don't buy any clothing on amazon that claims to be UV- protective (aka UPF 50+.) Have to pay for real brands that test their fabric.

This is accurate and very helpful to measure UV rays for my Turtle!

As stated in the title, this card works perfectly. I first tested the UV sensor under direct sunlight and it showed a very strong ultraviolet reading. I then exposed it to my UV-C lamp while protecting myself from exposure using gloves and a hood over the lamp. While the card is exposed to the lamp, I get a very strong green UV-C reading, and after a few seconds, the ultraviolet sensor began to indicate the strength. Once you remove the lamp, the UV-C sensor immediately turns off but the ultraviolet sensor continues to fade slowly. Again! The UV-C Sensor only glows during the exposure!If you have one or more UV-C lamps, this card will reassure you that they are working properly. Two previous lamps that I purchased did not have any UV-C or even an ultraviolet component at all and this card immediately exposed them as phony. They were simple LED Corn lamps that put out blue light.

There seem to be lots of items coming out of China that claim to have UV protection (window film, sunglasses, etc.) but don't have any. I was able to use this and find out that some window film I bought for a closet window did not in fact have any UV protection. I was also able to confirm that the sunglasses being used by my family are actually protecting our eyes. You don't want sunglasses to dilate your pupils and allow UV to flood in. Buying this was cheap insurance to protect us from damage to our eyes. I would definitely buy it again if I lost it.

It definitely worked for me

I bought this to test the UV claims of my ultrasonic cleaner and to see if the window above leaks UV. It worked very well and was worth the money for the piece of mind.

This helped me a lot in determining good anti-sun exposure products from the bad ones!

We are expecting a baby and have purchased a UV steriliser, then saw lots of warnings that some aren't actually emitting the correct wavelength. We purchased this card to check.As our steriliser doesn't have a window, we had to get a bit creative - using a phone recording it to check the right sections were glowing as expected (I'm glad to say they were).
