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).
Application:
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.
