Germicidal UVC light is an effective tool for eliminating pathogens on surfaces, but how do you know that the UVC dose is effective?
The UVC dosimeter™ for general use is a safe and efficient tool that can be used to verify UVC exposure of a surface, or an instrument, in a variety of environments, from hotels to restaurants to food and beverage manufacturing and processing facilities.
General purpose dosimeters verify you are delivering a UVC dosage high enough to reduce the microbial load on packaging materials, food products, and other contaminated surfaces targeted for disinfection. These UVC measurement and verification cards also provide you with real-time results that can be recorded, documented, and kept for future verification/validation purposes.
The technology consists of a photo-chromatic ink that changes color when it is stimulated by certain UVC radiation (253.7 nanometers). The central circle on the measurement cards changes from yellow to orange and pink, for E.Coli and Listeria doses respectively (includes instruction card).
