    UVC Dosimeter - 500/1000mJ - 254nm - Masks & Fabrics - 1 Square

    • $5.00
    Contact Us for Lead Time.

    UVC 1000 Dosimeters are designed to visually indicate an accumulated dose of UV-C up to 1,000 mJ/cm2, which is in the range recommended for decontamination of masks, due to the complex material they are made from. This also makes these dosimeters ideal when disinfecting any material with complex fabrics, including carpets, furniture, upholstery, and more.

    Using a patented, UV-sensitive material, our UVC 1000 Dosimeters react to UV-C radiation at 254nm and change color to indicate accumulated doses ranging from 500 to 1,000 mJ/cm2.

    According to a summary of research provided by the Centers for Disease Control on decontamination of masks for reuse, UVC delivered at a dose of ≥500 mJ/cm2 has been found to achieve 99.9% antimicrobial efficacy of pathogens similar to SARS-CoV-2. This includes Influenza A, Middle East Respiratory Syndrome (MERS-CoV), Sudden Acute Respiratory Syndrome (SARS-CoV), H1N1, and MS2 bacteriophage.

    Because surgical and other masks have complex woven fabrics, pathogens are easily able to escape ultraviolet germicidal irradiation, necessitating greater amounts of UV dose to deliver lethal amounts. Other textiles and fabrics can be similary complex, giving microorganisms a greater chance of survival. These can include upholstery in car and boat interiors, furniture in patient rooms and hotel rooms, and clothing that may be reused between washings.

    Little squares work

    I have these and the 100 dosimeters, and there's definitely a difference. These take a lot longer to change colors, so that must mean I'm giving them more UV dose?

    destiny n.

    Dosimeter squares are easy to stick on surfaces and reliable change color. Couldn't ask for much more. Gives customers a feeling of security to show we're disinfecting in accordance with CDC recommendations.

    Shipped quickly

    Shipped quickly and they work great. Thanks.

    Desperately needed dosimeters arrived safe

    We're using these exactly what they were designed for: disinfecting masks so we can reuse them. At 1000 mj/cm2, it's hard to tell how long to keep our ultraviolet lights on. Turns out, it was longer than we expected but less than the time we had been running them for (overkill theory on our part). So these helped us determine the right amountof time to run the lights.

    Dosimeter works as expected

    Arrived in a little bag packaged nicely. They have an adhesive backing so we can stick them on walls and objects in a room. Change color just as expected.
