UVC dose of 30 mJ/cm2 is needed for 99% reduction of SARS-COV-2 or COVID-19 coronavirus as per research done at Boston University*

*Signify and Boston University validates the effectiveness of UV-C light sources on inactivating the virus that causes COVID-19

The team applied a dose of 5mJ/cm2, resulting in a reduction of the SARS-CoV-2 virus of 99% in 6 seconds.

UVC indicators are intended for one-use-only and should not be reused.The indicator changes colour to indicate the level of UV-C irradiation on surfaces (254 nm)

Visibly demonstrates the accumulated dose of UV-C irradiation on a surface. Especially useful in shadowed areas.

When exposed to an appropriate dose of UV-C, the yellow area changes to orange and shades of brown depending on the dose. Our indicator has colour change corresponding to a dose of 50 mJ/cm2, 100 mJ/cm2, 150 mJ/cm2 and 200 mJ/cm2

Recommended for use with UV-C disinfection systems in healthcare facilities, physician and dental practices, commercial spaces and more.

Great for in-servicing, training, validating UV-C lamp performance, and as a simple reporting tool for Infection Control and Environmental Services.

Most healthcare facilities do not have the means to measure UV-C to determine if effective doses are being delivered. The colourimetric indicators provide an easy means to monitor UV-C dosing.

Ultroz UVC Indicators are recommended for each UV-C disinfection cycle to visually determine if surfaces have received an optimal level of germicidal irradiation.

• Place the Ultroz UVC indicator on or adjacent to surfaces or equipment that will be disinfected with ultraviolet germicidal irradiation. The dosimeters can be placed in a horizontal or vertical position.
• Always make sure the yellow colour-changing area faces toward the UV-C light source.
• With sufficient UV-C exposure, the yellow area will change to orange and shades of brown, providing a visual indication that the surface has received a UV-C dose that can be correlated to dose of 50 mJ/cm2, 100 mJ/cm2, 150 mJ/cm2 and 200 mJ/cm2
• Verify exposure of the Ultroz UVC Indicator and make any additional notations on the card or elsewhere to document the colour change.
• Make exposure readings within 24 hours after the UV-C disinfection cycle.
• Retain or discard the used dosimeters in accordance with site requirements.
• Ultroz UVC indicators are intended for one-time-use only and should not be reused.
