What is QuantaDose™?

QuantaDose™ UVC test card Is made durable with a standard PVC credit card thickness of 0.76 millimeters (1⁄32 in).

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™ 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.

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™ 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 250-275nm are shown in green.

Top Light Sensor Test Wavelength of UV Exposure: When exposed to optimal UVC germicidal wavelengths, the QuantaDose test card undergoes an instant color change to a green where fluorescence is directly related to the energy value received. Fluorescence stops when excited electrons release all photos within nanoseconds after exposure.

Bottom Light Sensor Test Intensity of UV Exposure: When exposed to UVA, UVB, and UVC wavelengths, the QuantaDose test card undergoes a gradual color change to purple, changing from clear to light purple and dark purple directly related to intensity or the energy value received.  When under germicidal light the word ULTRAVIOLET appears at between 300-500 Microwatt per square meter [µW/cm²].   Photochromic dosimeter color is temporary for checking UV intensity after exposure and should be checked immediately after exposure for the most accurate intensity results.

• Verify the wavelength of light being emitted
• Validate the amount of light being emitted
• Confirm the amount of light reaching a surface

Ultraviolet light can be detected in several ways, professionals sometimes use Ultraviolet light meters that cost several hundred dollars, upwards to several thousand dollars.

The QuantaDose™ UVC Detection Card uses a specially formulated ink chemistry that is designed to be sensitive to only shortwave ultraviolet radiation (Germicidal UVC), not visible light or UVA and UVB. This ensures only germicidal wavelengths are being detected in the top sensor test area, while the other UV test sensor area covers a wide UV spectrum of UV intensity using a reversible dosimeter that detects UV between 200-400 nm from the lower test strip area on the QuantaDose™ UV Test Card.

UVC-producing germicidal lamps must be monitored as we are counting on these light-emitting devices to potentially save our lives and it is very important to ensure that the germs are receiving a lethal dose of Ultraviolet-C radiation.

These easy-to-use, credit card-sized UVC Dosimeters/Indicators will increase the efficiency of the UV light disinfection processes by helping you visualize what is most effective.

The amount of inactivation is directly proportional to the UVC dose, which is received, and this in turn is the result of its intensity and duration of exposure. The farther away from the light source, the less UVC will reach the target, so only a quarter of the UVC remains when the distance doubles.

With an increasing number of fake and defective products on the market, Ultraviolet Dosimeters provide you with real-time results for verification/validation purposes.

The dosimeter uses a specially formulated ink that is designed to be reactive to shortwave ultraviolet radiation (UVC), not visible light or UVA and UVB.  This ensures only germicidal wavelengths are being measured in the dosimeter test area.

There has not been an easy and economical way to visualize the UV disinfection process that has been cost-effective for everyday consumers of UVC germicidal light products.  QuantaDose™ can help calculate a satisfactory level of UVC energy at recommended power intensities and verify the most important factor of UV disinfection – that the UV wavelengths being used are actually optimal for germicidal lighting.QuantaDose-UVC-test-card-measures-UV-UVC-intensity-uvc

People don’t live in medically staffed clean rooms, so an effective dosage under current CDC PPE disinfection guidelines for Ultraviolet germicidal irradiation (UVGI) is 1,000 – 3,000 mJ/cm2 to ensure 99.9% deactivation when dust, moisture, and other particulate matter is present, such as fiber filtration used in face-masks.

The QuantaDose™ will have a noticeable color change that occurs between approximately 300-500 Microwatt per square meter [µW/cm²] in the lower dose-response area under direct 253.7 nm UVC light. This is on the lowest end of acceptable UVC power intensities allowed under the CDC’s newly updated recommended guidelines for using UVGI in a rapid disinfection process of between 5 and 10 minutes.

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 power from the UV light is likely not reaching the desired level of germicidal intensity required under CDC guidelines.

At an intensity of approximately 3000 µW/cm² of direct 253.7 nm UVC light, the QuantaDose will achieve maximum color concentration in about 15 seconds, the first signs of the word ULTRAVIOLET indicate an intensity of approximately 300-500 µW/cm².

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

The top UVC indicator confirms the correct germicidal wavelengths are present, simultaneously the bottom UVC indicator detects germicidal irradiation intensity with an increased color concentration around the word ULTRAVIOLET.

The bottom UV dosimeter intensity section is reactive to wide-band UV between 200-400 nm capable of detecting UVA/UVB and UVC wavelength.

This allows your QuantaDose™ card to also work for gauging the SUN’s UV intensity so you can take necessary precautions such as sunscreen or shade.

QuantaDose™ is easily the most versatile UV/UVC test card in the world!


These easy to use QuantaDose™ UVC Detection Cards give you what you need to start validating UVC light output from your untested UVC light sources. It’s not enough to trust the manufacturer’s specifications.  You must verify that the system of UV-C Light you’re entrusting the health and well being of your family and loved-ones is functioning as advertised and produces UV light capable of deactivating germs and killing pathogens.
