The Signoscope T3 is the further development of the SAFE-Signoscope, the first optical-electrical watermark finder and testers that are in use thousands of times worldwide.

The device works completely without chemicals and thus without risk for the stamp.The handling is very simple. They detect not only watermarks but also repairs, degrees of preservation, quality defects and paper irregularities. This in a new, fascinating way:

The new Signoscope T3 has become much more powerful; It works with 3 strong LED’s, which are hardly susceptible to wear and very energy efficient. These LED’s guarantee optimal illumination of the stamp. The Signoscope T3 brings to light what was previously hidden and makes watermark differences visible, which may mean a significant value difference of the stamps. The LED light sources are infinitely dimmable. You will find optimal illumination for every stamp to be tested, as it is not always said that maximum exposure to light will bring out the watermark optimally. Adjust the intensity of the light sources by moving the control knob up and down (+ and -).

In addition, the stamp can be examined with multiple light colors, which in turn are all dimmable. Watermarks, paper irregularities or even repairs can appear differently depending on the light color and can also be better recognized. Multiple RGB colors: violet, blue, cyan, green, yellow, brown, red and 3 different whites (bright white, soft white and daylight white)

These different colors can significantly improve the examination result by, for example, irradiating a (mainly) red-grounded mark with red light, thereby virtually “neutralizing” the red printing ink, which may appear on the back of the stamp. The watermark now appears more clearly and is no longer disturbed by unwanted color effects. There is also a Power Bank that you can buy separately if you want your T3 to be portable.
