If you’re fighting SARS-CoV-2 with UV-C, our dosimeters can help you win the battle.


UVC Dosimeters change color
when exposed to UV-C energy…

…so you can independently validate your devices and procedures to SEE if an optimal dose of UVGI has been delivered to a surface. A recent study from Boston University and Signify has shown that SARS-CoV-2, the virus that causes COVID-19, can be inactivated by UV-C in 25 seconds with a dose of 22 mJ/cm². Click to read. Having a visual indication of dose is critical for the success of your UV-C disinfection protocols. UVC Dosimeters are recommended for use during every disinfection cycle to provide visible confirmation and confidence for staff, patients, visitors and guests.
UVC 100 dosimeters

UVC 100 Dots

UVC 100 Dosimeters are available as 1″ dots with an adhesive backing. The dots can be placed on a variety of surfaces and will change color when exposed to UVGI at 254 nm. Ideal for use during room and surface disinfection with UVC towers, fixed ceiling units, conveyor systems, cabinets or hand-held disinfection units.

UVC 100 dosimeter cards

UVC 100 Cards

UVC 100 Dosimeter Cards feature a yellow indicator, surrounded by two reference colors (orange and pink) to indicate UVGI doses of 50 and 100 mJ/cm². The have an adhesive strip and write-in areas to capture date, time, operator name as well as location of card placement to document each UVC disinfection cycles.

UVC 1000 dosimeters

UVC 1000 Squares

UVC 1000 Dosimeters are 1″ square stickers that will color-indicate UVC exposure in range of 500 to 1,000 mJ/cm². These dosimeters are intended for use during UVC decontamination of N95 masks. According to guidance from the CDC, UVGI delivered at ≥500 mJ/cm² can achieve 99.9% disinfection.

Note: Product packaging and dosimeter card designs may vary by region and distribution partnerships.
