A UV water purifier treats micro-biologically unsafe water with germicidal ultraviolet light. The UV wavelength scrambles the DNA of living organisms in the water, so they can no longer reproduce and make you sick. If you drink bacteria-infested water, the organisms can embed in your digestive tract and replicate. Ultraviolet radiation renders bacteria, viruses, parasites, and fungi unable to replicate by damaging the nucleic acids of their DNA. 

UV dosage is the measurement of energy (in mJ/cm2) delivered by a UV water purifier. The more dosage provided, the more energy delivered to treat contaminated water. At a certain threshold, this energy becomes sufficient enough to inactivate most of the microorganisms present in water.

This system offers outstanding control, high-precision and USP-complying conductivity measurement with temperature compensation that can be switched on or off.
