Metal Markers

Several metals were tested with positive labeling results. In the picture below we have the marking of metallic scissors.

Several metallic cylinders used for gas conditioning have been tested with positive results. In the figure below we have the marking of oxygen metal cylinders. The figure below shows the photos of the marked cylinders when subjected to laser excitation. Here you can see the presence of a green color that is characteristic of the MARK1 used in the tests.
