The key of the system is Borer machine, specially designed.
It drills a crater-shaped hole with clean and velvety
depth on paint surface in material (See figure). Its
depth is feasible to adjust according to the coating
and basic material.
Put the bored sample under microscope, the crater can
be seen by a high-resolution monitor. You can check
easily metal surface, ground coating, paint layer and
other multiple coating layer, and measure the thickness
of coating. This device is a standard of coating thickness
measurement from ASTM D5796, and it provides much more
accurate precision than magnetic field and eddy current
measurement device, used most commonly, since it measures
thickness of coating physically.
It also features to use quality inspection of product
without any certification since it has been used as
international standard device.
