Ultraviolet (UV) is a kind of electromagnetic wave whose wavelength is between 100nm and 380nm. The ultraviolet wave band with disinfection ability is between 200nm and 280nm.
After ultraviolet disinfection of ultraviolet disinfection, the ultraviolet energy absorbed by the pathogenic microorganism at 200nm ~ 280nm, the mutation of its genetic material (nucleic acid) causes the cell not to divide and multiply any more.
UV INTENSITY UV INTENSITY UV energy received per unit area of time perpendicular to the direction of UV propagation. In this standard, UV intensity is used to describe the UV energy of UV disinfection equipment. Unit Common mW/cm2.
UV TRANSMITTANCE UV transmittance (UVT) the ratio of the UNABSORBED UV rays to the total UV output at 253.7 nm. UV dose the amount of UV energy received per unit area of UV dose, usually in millijoule per square centimeter (mJ/cm2) or focal per square meter (j/m2) .
Device UV average dose reactor average dose, or AD, reduces the UV lamp to a point source, then calculates the average UV intensity in the sterilizer using the point source cumulation method, multiplied by the average exposure time to get the dose.
The average dose is the theoretical dose of ultraviolet disinfection equipment, which is usually calculated by UVDis calculation software, so it is sometimes called UVDis dose.
The effective dose of ultraviolet (UV) of equipment is the microbial inactivation UV dose that can be achieved by ED UV disinfection equipment, or the biological test dose of UV disinfection equipment, collectively referred to as the effective UV dose of equipment.
UV Dose Response Curve (UV Dose Response Curve) reflects the relationship between the inactivation or disinfection of a microorganism and the UV dose received. Inactivation is usually expressed as log10(n) or log10(n/n 0) , where n 0 is the pre-uv microbial content and n is the post-uv microbial content.

UV Lamp Aging Factor CLH lamp aging factor ratio of the UV output power at the end of the lifetime of the UV lamp to the UV output power of the new UV lamp. Scaling Factor CJG lamp fouling factor ratio of the UV transmittance of the UV lamp sleeve in use to the UV transmittance of the clean UV lamp sleeve.
UV Lamp Operating Life Operation Life of UV lamp effective output continuous or cumulative operating time. UV STERILIZER UV disinfector can be used to irradiate cavities and containers.
