QuantaDose™ Dual wavelength photochromic intensity indicators are a basic, reliable, low cost, simple, in-house method of monitoring UV intensity along with verifying UVC radiation.

  • Verify the wavelength of light being emitted
  • Validate the amount of light being emitted
  • Confirm the amount of light reaching a surface
  • Detect between 200-400nm UVA/UVB on one scale, and 200-275nm UVC on another from the same reusable UV test card

quantadose-uv-light-test-tell-if-uv-light-is-workingWith an increasing number of fake and defective germicidal UVC products on the market QuantaDose™ provides you with real-time results for super fast verification/validation purposes.

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

Increase the efficiency of UVC light disinfection and UV safety

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

When exposed to UVC germicidal wavelengths between 250-275nm, the QuantaDose™ test card undergoes a rapid color change to green where fluorescence is directly related to the energy value received.

Multiple Usage Scenarios

QuantaDose™ the most versatile UV/UVC test card on the market today. Gauge when the sun’s natural UVA/UVB radiation warrants protection and test that your germicidal UVC lighting performs as advertised.

Simultaneous UV Detection


QuantaDose™ is the only UV intensity card meter that distinguishes between the sun’s natural UVA/UVB radiation and man-made sources of germicidal UVC wavelengths simultaneously.

UVA/UVB Detection


UVA comprises of almost 95% of the light that reaches our skin, UVB makes up the rest. The FDA and World Health Organization have all declared UV radiation a known carcinogen. Natural and artificial sources.

UV-C Detection

Specially formulated ink chemistry that is sensitive to only UVC will not fluores to visible light or UVA and UVB. This ensures only germicidal wavelengths between 254-280nm are being shown in green.


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. Get the strength by quantifying UV power with QuantaDose™!

Two Different Ink Technologies In One UV Test Card

Fluorescence is the emission of light by a substance that has absorbed light or other electromagnetic radiation. It is a form of luminescence. In most cases, the emitted light has a longer wavelength, and therefore lower energy, than the absorbed radiation. Fluorescent materials cease to glow nearly immediately when the radiation source stops, unlike phosphorescent materials, which continue to emit light for some time after.

Phosphorescence is a type of photoluminescence related to fluorescence. Unlike fluorescence, a phosphorescent material does not immediately re-emit the radiation it absorbs. The slower time scales of the re-emission are associated with “forbidden” energy state transitions in quantum mechanics. As these transitions occur very slowly in certain materials, absorbed radiation is re-emitted at a lower intensity for up to several hours after the original excitation.


What is a UV/UVC testing card?


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 Cards.

The dual feature of the QuantaDose 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 such a consumer friendly assessment tool by allowing them to be used over and over again.

Germicidal UVC light is an effective tool for eliminating pathogens on surfaces and in the air, but how do you know that the UVC dose is effective? How do you know if you purchased an effective or even real UVC disinfectant light from Amazon, ebay or any-other online retailer that allows 3rd party resellers willing to take advantage of the current pandemic.

The technology QuantaDose™ uses consist of a photo-chromatic ink that changes color when it is stimulated by certain UVC radiation (Top UV Indicator Strip: 222- 280 nanometers. Bottom UV Indicator Strip: 250- 400 nanometers ).
