Main highlights

The device comes with a USB adapter and can be connected to the mains or to a computer with USB port.
The Signoscope works with 3 strong RGB LEDs (= 9 LEDs), which are very energy-saving and hardly susceptible to wear. The continuous adjustment of the light intensity (+/-) allows optimal illumination of the respective brand, whereby maximum light irradiation does not necessarily bring an optimal test result.
In addition, 3 different heat levels of white light are available as central examination lights.
For mobile operation of the Signoscope PRO, we recommend our SAFE power bank no. 9894. It is very space-saving and the housing is made of aluminium. The capacity is 2600mAh (not included).
8 different colours and 3 different day-white lights, as central examination lights, can be adjusted. The colours can improve the results of the examination by e.g. a red-based brand is irradiated with red light and thus the red printing ink, which may on the back of the brand, "neutralised". The watermark, repair... are not disturbed by unwanted colour influences and are more noticeable.
