Visibly demonstrates the accumulated dose of UV-C so you can confirm that a surface has received an optimal level of germicidal irradiation. A recent study indicates that SARS-CoV-2 can be inactivated by a dose of 22 mJ/cm². Click to read.

PLEASE NOTE: This product can be used with UV-C LED devices producing irradiation in the range of 260 nm – 280 nm.

UVC Dosimeters are an important tool to achieve optimal UV-C disinfection by enabling operators to:

Determine the dose delivered at varying distances from the device
Identify shadowed areas that may require device repositioning
Optimize run-times for efficiencies in disinfection cycles
Provide evidence of disinfection cycles for credentialing, auditing and data collection

To use, peel off the protective strip to expose the adhesive and place the dosimeter on or adjacent to any equipment or surface that will be disinfected with ultraviolet germicidal irradiation. Make sure the yellow indicator area faces toward the UV-C light source.
After the disinfection cycle is complete, the colour-change allows you to see if you’ve reached 25, 50 to 100 mJ/cm².
UVC Dosimeters are intended for one-use-only and should not be reused. Store at room temperature and away from direct sunlight.

This product is recommended for use with UV-C disinfection systems in all public locations including:
