What is a QuantaDose™ UVC test card?

The all new 2020 QuantaDose reusable UVC test card! (2nd Edition Shown)

The world’s first UVC intensity test card with UVGI wavelength indicator.

REUSABLE (>1000 15 Second Exposures @ 300 µW/cm)

QuantaDose™

QuantaDose™ UVC test cards are a pre-calibrated UVC light wavelength and intensity instrument to get a rapid visual reference of both UVC intensity and UVC wavelength that is being used with UVC test results completed in only seconds!

QuantaDose™ UVC test cards are the world’s first and only 2-in-1 UVC Test Cards combining two results for accurate UVC intensity readings from specially designed reusable UV wide-band analytes.

It is important that the lower UVC intensity gauge is used in tandem with the top wavelength indicator to confirm that you measure UVC intensity from a real source of UV-C wavelength light. This part of the test is instant! The glowing letters “UV-C” will only glow when exposed to 220-270 nm -+ 5 nm indicating the wavelength is germicidal – this is not indicative of power or intensity. This is measured in the lower test card area.

Only after seeing the instant pre-calibrated UVC wavelength reaction on the UVC test cards top UV-C wavelength Indicator. Represented by the letters “UV-C” glowing brightly. This confirms the detection of light between 250-275 nm -+ 5 nm.

Now that UVC wavelength is confirmed, the next step is UVC intensity testing, this is the most helpful part of the UV test card. This informs you if the UVC intensity is powerful enough to disinfect over the time-frame you require.

Besides creating breakthrough wide-band reversible analytes, the biggest breakthrough came in the form of a simple inverted word. This inverted word turned out to be the most important part of visualizing UVC intensity test card calibration points, and confirmation of reaching a pre-calibrated UVC intensity level of 300 µW/cm² to reference for UVC dosage calculations.

The QuantaDose™ UVC intensity test card relies on the word ULTRAVIOLET becoming visible starting at 300 µW/cm² when exposed to UVC light between 250-270 nm (UV-C will be visible in the top indicator)

The UVC Test card’s photochromic color change exhibits a reversible UV/UVC intensity gauge that first displays the word ULTRAVIOLET at 300 µW/cm². When we were designing the QuantaDose™ we had to ensure the accuracy of visualizing closely calibrated UVC intensity levels for meaningful reference.

What we found was that everyone could perceive shades of colors very differently when dealing with light colors with little differences between shades, but big differences in intensity between these shades.

Yet, a word always becomes visible to everyone’s eyes at about the same time providing your vision is good enough to drive a car legally.

This is why QuantaDose™ has chosen word visibility over color differentials to visualize UVC at a minimum calibrated UVC intensity level of at 300 µW/cm² when the word ULTRAVIOLET becomes visible under a confirmed UVC wavelength of 250-270 nm.

For consumers that purchase this product for a single time use to test a UVC light product, We have boxed in our wide-band UV analyte to include a UV sun gauge, so the card continues to be useful.

QuantaDose™ is a photochromic intensity and wavelength indicator card that is a reusable, essential, reliable, low cost, simple, in-house method of quickly monitoring UV intensity along with verifying optimal UVGI wavelengths.

This product has many uses! Initially designed for fully protected UV light installers, UV sanitation workers, and homeowners to quickly visualize their UVC disinfection grid for the fastest, most effective UV lamp set up time.

Using the QuantaDose™ rapid visualization technology before the final use of expensive single-use medical-grade irreversible testing cards can help you avoid wasting money on blindly guessing UVC lamp placement for a timely lethal dose of UV exposure.

Now millions of consumers that have purchased UVC products have a cheap and easy way to see if what they paid for is UVGI that a hospital would trust for rapid disinfection in under 10 minutes. The world’s only UVGI rapid test intensity test card.

QuantaDose™ professional-grade reversible UVC test cards are not designed to replace medical-grade irreversible photochromic pigment cards, QuantaDose™ is a quick reference tool to help prevent waste of expensive single-use UVC dosage cards with an early indication before going through the time of running through a full cycle!

While it is not difficult to calculate dosage when you know intensity at any given distance from the UV source.

We highly suggest irreversible UVC test cards should be used for confirming 50 and 100 mJ/cm² accumulative exposure dosage over the entire time of the UVGI disinfection process for either commercial or home environments as final confirmation.

UVC Dosimeter Test Cards vs UVC QuantaDose Intensity Test Cards vs UVC Indicator Test Cards

QuantaDose-UVC-test-card-measures-UV-UVC-intensity-uvc

QuantaDose™ minimum intensity readings give you the ability to calculate dosage at any given distance, it is even very helpful under reflective conditions.

When you know the UVC intensity at any giving point of known distance, QuantaDose™ can provide the necessary variables needed to calculate accumulated dosage overtime at different distances.

The inverse square law of distance can be used to calculate UVC intensity that is directly proportional to the distance of the direct line of sight from a UVC light source when longer disinfection times (Under 300 µW/cm²) are used to reach target areas as a result of being farther away from a UVC light source.

The video here is quantifying the QuantaDose™ UVC Rapid Test with American Ultraviolet UVC Dosimeters by Intellego Technologies and General Tools UV512C UVC light meter.

The video clearly shows UVGI wavelength and the minimum of 300 µW/cm² was confirmed by QuantaDose™ intensity gauge for rapid disinfection.

At the distance seen, the 35-watt UVC bulb peaked at 350 µW/cm² at full operating temperature. Notice QuantaDose™ color when exposure reaches 300 µW/cm² as the bulb warms up to reach the minimum intensity for a color reaction to occur.

At this intensity, a 100 mJ/cm² accumulative exposure is reached in 5 minutes as confirmed with American Ultraviolet’s UVC Dosimeters by Intellego Technologies and the real-time readings in µW/cm² are provided with a General Tools UV512C UVC light meter.

Start increasing the efficiency of UVC light disinfection and UV safety with a new visual perspective!

QuantaDose™ UVC test cards are reusable but not invincible, over time photochromic analytes will degrade from high energy UV exposure.

QuantaDose™ offers a package for UVC installers and the avid UVC light tester, it includes 5 QuantaDose™UVC test cards and a FREE 3 Watt UVC light wand for UVC test card calibration. By simply holding a 3 watt light one inch away will advise you if your card is still suitable for UVGI intensity testing.

Increase the efficiency of UVC light disinfection and UV safety

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

This easy-to-use, credit card sized 85.60 mm by 53.98 mm (3 3⁄8 in × 2 1⁄8 in) UV/UVC light test card is an economical way to visualize within 15 seconds when the UV disinfection process will truly deliverer a powerful level of UVC energy to the target for sterilization in under 10 minutes.

QuantaDose utilizes fluorescence for wavelength indication which is an excitation spectrum caused by light absorption and an emission spectrum from the light emitted/reflected by the wavelength UV/UVC test area. The color concentration of the QuantaDose’s specialized intensity test area is directly proportional with the intensity of the UV emission. Great for Testing UVC Lights to expose fake or lights below acceptable intensity levels for rapid disinfection.

When exposed to UVA, UVB and UVC wavelengths, the QuantaDose™ test card undergoes a gradual color change from clear to light purple and dark purple that is directly related to the energy value received.

When exposed to UVC germicidal wavelengths, the QuantaDose™ test card undergoes a rapid color change to green where fluorescence is directly related to the energy value received.

What are Ultra Violet (UV) rays?

UV is an electromagnetic ray wave spectrum from 100 to 400 nm (nanometer). This spectrum can be separated in UV-A, UV-B & UV-C. UV-rays are a part of natural light from the sun.

UV-A and UV-B is already well known for causing suntans and the creation of vitamin D3 within our bodies and the unfortunate skin cancers and aging effects after years of sunlight exposure.

Knowledge of UV-C is less spread, because these very powerful shortwave rays normally do not reach us through the protective earth’s ozone “shield”. While UVC light doesn’t make to the surface of earth naturally, fortunate for our everyday lives its power has been harnessed, and we can instrumentality create UV-C with special light bulbs or deep UV LED’s as very effective disinfectants without leaving toxic waste chemical detergent residues behind.

UVC light is one of the best sterilization methods available today, so it is important to ensure your UVC devices are working properly and at the most effective germicidal wavelengths when depending on UV light disinfectant technologies for the safety of your family, friends and co-workers.

  • Verify the wavelength of UVC light being emitted from a germicidal UV device.
  • Validate UV light intensity being emitted.
  • Confirm the amount of germicidal UV light reaching a surface for disinfection.
  • Detect between 250-400nm UVA/UVB on one scale, and 200-275nm UVC on another from the same reusable UVC light test card.
  • Multi-analyte constituents provide fast chromatic analytical data for UV testing.
  • A simple tool for pandemic countermeasures to ensure use of desired optimal germicidal wavelengths.

Disinfect Visually

QuantaDose™ eyes-on innovation

The amount of pathogenic inactivation is directly proportional to the UVC dose and this in turn is the result of UVC intensity and duration of UVC exposure. The farther away the light source, the less UVC will reach the target, so UVC intensity is reduced to a quarter when the distance doubles. Quantify your UV power with QuantaDose™

HOW DOES UVC DESTROY GERMS?

uvc-light-dna-rna-damageThe high energy from short wavelength UVC light is absorbed in the cellular RNA and DNA, damaging nucleic acids and preventing microorganisms from infecting and reproducing. This absorption of UVC energy forms new bonds between nucleotides, creating double bonds or “dimers.” Dimerization of molecules, particularly thymine, is the most common type of damage incurred by UVC light in microorganisms. Formation of thymine dimers in the DNA of bacteria and viruses prevents replication and ability to infect.

QuantaDose™ UV/UVC Photochromic Test Card

Also referred to as UVC Indicator Strip, UV Germicidal Test Strips, UVC Reactive Strips, UVC Dosimeter Strips, UVC Dosimeter Cards, UVC Intensity Labels, UVC Test Strips, UV-C Test Card, UVC Indicator Card, UVC Light Test Strips, UVC Detector, UVC Test Kit, UVC Visualizer Strips, UVC Visualizer Strips and most accurately called a Photochromic UVC Measurement Test Card.

The CDC website link here recommends using direct Ultraviolet germicidal irradiation (UVGI) @ 0.5–1.8 J/cm2 in very clean environments to be effective against Influenza A (H1N1), Avian influenza A virus (H5N1), Influenza A (H7N9), A/Anhui/1/2013,Influenza A (H7N9),A/Shanghai/1/2013,MERS-CoV, SARS-CoV, H1N1, Influenza A/PR/8/34, MS2 bacteriophage with antimicrobial efficacy 99.9% for all above tested viruses.

However most people don’t live in medical staffed clean rooms, so an effective dosage under current CDC disinfection guidelines for Ultraviolet germicidal irradiation (UVGI) is 1,000 – 3,000 mJ/cm2 to ensure 99.9% deactivation when dust particles can be present.

The QuantaDose will have a noticeable color change that occurs between approximately 300-500 µW/cm² in the lower dose response area under direct 253.7 nm UVC light. This is on the lower end of UVC power intensities allowed under the CDC’s recommended guidelines for using UVGI for rapid UVC disinfection.

If you are not getting a color change displaying the word ULTRAVIOLET in the lower section of the Quantadose test card while the UV-C indicator is green the UVC light is likely not reaching the desired level of germicidal intensity required under CDC guidelines.

At an intensity of approximately 3000-5000 µW/cm² 253.7 nm UVC the QuantaDose will achieve maximum color concentration in about 15 seconds.

It is important that BOTH QuantaDose indicators have visible color distinction when confirming effective UVGI intensity from consumer grade UVC lighting.

What is a UVC testing card?

The dual feature of a UV and UV-C test card is based on the principle of molecular change when excited with high energy wavelengths of light. When the energy of a photochromic molecule absorbs energy from sunlight and ultraviolet light, the structure of the molecule changes and photons are reflected at a shorter wavelength, resulting change in the reflected light’s wavelength ultimately changes the color of the substance. When the energy from sunlight or ultraviolet UVC light is released, the molecule returns to its original structure and the color returns to its original color. This temporary change in reflected light is what makes QuantaDose™ photochromic UVC measurement cards so consumer friendly allowing them to be used over and over again.

Your continued support will help us make photochromic analytes more durable and way more helpful than ever before! Thank you! From all of us at QuantaDose!

Using UVC light technology will not leave residue after treatment, and having a broad spectrum of action and rapid exposure times. The germicidal effects of UVC irradiation results in cellular damage by photohydration, photosplitting, photodimerization, and photocrosslinking, thereby inhibiting cellular replication.

Today’s easy to use compact UVC technology allows us to fight the virus outside our bodies like never before! We live in a world dominated by third party sellers on Amazon, ebay and Walmart platforms with absolutely no accountability to consumers that purchase these fake germicidal lighting products.

That said, questions about UVC disinfection do arise. How to tell if your UV sterilizer is really working? How to test UV light effectiveness? How to tell if UV sterilizer is real?

Checking if a UV sanitizer is real or fake UVC is easy with a QuantaDose™ UV test card!
