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 when the UV disinfection process has truly delivered a powerful level of UVC energy to the target for sterilization.

QuantaDose utilizes fluorescence spectrometry which is an excitation spectrum caused by light absorbed by an analyte (UV test strip) and an emission spectrum from the light emitted/reflected by a multi-analyte UV/UVC test area. The color concentration of the QuantaDose’s specialized analyte is directly proportional with the intensity of the UV emission.

Increase the efficiency of UVC light disinfection and UV safety

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

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

What are Ultra Violet (UV) rays?

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

UV-A and UV-B are already well known for causing suntans, creating 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 potent shortwave rays normally do not reach us through the protective earth’s ozone “shield.” While UVC light doesn’t make it to the surface of earth naturally, fortunate for our everyday life are its power has been harnessed, and we can instrumentalize UV-C with special light bulbs or deep UV LED’s as the most effective disinfectants without leaving toxic waste chemical detergent residues behind.

UVC light is one of the very best sterilization methods available today. Hence, 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.

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 Detectionhttps://www.quantaspray.com/wp-content/uploads/2021/01/uvc-light-confirmed-300×194.jpg

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

https://www.quantaspray.com/wp-content/uploads/2021/01/uv-no-uvc-light-quantadose-300×194.jpg

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

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®!

Easily evaluate and compare multiple UV/UVC light sources

Monitor UV/UVC exposure in difficult-to-access environments

Simple and real-time method to measure the sun’s ultraviolet index

The color deviation can easily be measured for general UV analysis

The UV-C indicator strip/label is a narrow band UV-C photochromic product

Purple ink is photochromic at 320-400nm and green ink between 254-280nm

HOW DOES UVC DESTROY GERMS?

The 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.

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.

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.

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! 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 UV sterilizer is working? How to test UV light effectiveness? How to tell if UV sterilizer is real?

The answer to how to check if a UV sanitizer is real or fake is easy with a QuantaDose® UV test card!
