If the high accuracy of electronic coating thickness measuring instruments is not necessary, the LEPTO-Pen is the simple and economic alternative: The LEPTO-Pen works on untempered commercial quality steel substrate according to the known magnetic attraction principle (EN ISO 2178).
The surface to be measured must be free from dust, oil or other pollution.
-Place the LEPTO-Pen perpendicular to the surface so the magnet sticks to the surface.
-Then pull the LEPTO-Pen slowly and with calm hand perpendicularly from the surface and watch the scale deflection.
-The scale deflection value immediately before detaching of the magnet corresponds to the coating thickness to be measured.
