A UV Tester can be used to inspect the Fluorescence of e.g. stamps, banknotes, credit cards and more. You check the fluorescent authenticity characteristics of Banknotes to distinguish the original from the counterfeit or in the case of Postage Stamps checks the illumination of Phosphorus stripes or an L profile.
Postage stamps contain phosphorus to enable automatic sorting at the post office. The first stamps with phosphorus appeared in Britain in 1959 as a replacement for stamps with graphite. There are a large number of stamps available with and without phosphorus. It can be very useful to be able to make this distinction in your collection, and there is often a difference in value between the two. Some stamps from these countries have a different way of applying the phosphor, so the phosphor lights up with a different frequency. If you want to be absolutely sure, it can be helpful to use both long wave and short wave with certain countries.
You need the short wave at least for Great Britain, Israel and United States. There are 3 types of UV, namely UC-A the most common long wave, 315-400 nm, UV-B this is only used for other purposes, 280-315 nm, UV-C the short wave, 100-280 nm.
This UV Tester L92 is a complete top-quality multitester that provides the user with a number of features. The built-in, durable ultraviolet LED has a wavelength of 254 nm (short wave), which means that this device can detect and check phosphorescence. Even stamps with paper repairs can be checked with the UV lamp. Moreover, the UV LED used is extremely powerful and gives good results, including afterglow of phosphorescence.
This Tester can also be used as a magnifying glass. On the top side you have a magnifying lens (2x magnification) to better observe details.
