Unraveling Velleman Zluv220: From Full Specifications To Potential Issues
Velleman ZLUV220 Information The Velleman ZLUV220 is a counterfeit money detector that uses ultraviolet (UV) light to reveal security features that are not visible to the naked eye. It is a small, portable device that can be used by businesses, retailers, and individuals to check the authenticity of banknotes and credit cards. The ZLUV220 has two UV lamps that emit a wavelength of 365 nanometers. This wavelength is specifically chosen because it is absorbed by most security features found on banknotes and credit cards. When the ZLUV220 is turned on, the UV lamps shine on the surface of the money or card, causing the security features to glow. These features can include watermarks, microprinting, and security threads.
