During the UVC hygiene process, the UVC light targets the DNA of the microbe. The UVC light, particularly the 250-270 nm wavelength, is readily absorbed by the microbial nucleic acids and is considered the lethal wavelength for microbes. The UVC wavelength of 253.7 nm is termed as the germicidal spectrum as it is the most lethal wavelength for microbial inactivation.
Another vital aspect is different types of hygiene target will require a different level of dosage of UVC to be reduced or killed, but the UVC light conversion rate, the distance between the light source and surface, and exposure will affect the energy accumulated on the target surface eventually. And what’s more, the working condition of the UVC device and power voltage input also drive different UVC light conversion rates. We safely concluded the importance and necessity of using a dosimeter for UVC devices, especially household and personal operation.
By directly opposite putting one uvc dosimeter test card against any personal or household uvc sterilizing, sanitizing or disinfecting device light source, our UVC dosimeter test cards visibly changing color by 6 level purple gradient.
The color changed due the different levels of accumulation of UVC irradiation (energy), will visually and readably help any household uvc disinfection operator or personal uvc sanitizer user to recognize if the surface intended to be disinfected or sterilized have received enough energy to kill/reduce various kind of bacteria, virus and spores including the most common MRSA and C.Diff etc.
Making sure the sufficient uvc dosage has been delivered the surface or space intended to be disinfected or sterilized is the key point to guarantee a effective and sufficient disinfection process.
That’s why we recommend, and it’s actually vital, to use our uvc dosimeter test cards for every single household disinfection or personal sanitizing, because the uvc dosage deliver and energy is complicatedly correlated with exposure time and distance between the light source and surface, which is impossible to make accurate judgement by human eyes or simple counts of seconds.
The coming user instruction in uvc dosimeter test cards box has a list to help you lean what kind of bacteria, virus and spores commonly existing in kitchen, bathroom, public place etc can be reduced up to 99.99% with different dosage level. The related information are sourcing from uv-light.co.uk.
UVC has been proved one of the most effective and economic method for household and personal disinfection, sanitizing or deep cleaning, but rare brand or product support a result visible disinfection or sanitizing experience.
With providing valuable proof of effective disinfecting operation and output power of the UVC device, our UVC Dosimeter cards allow every user to confirm how much germicidal irradiation has been delivered and accumulated on the surface, and check whether the disinfection process effective or not Quickly and Easily.
