1.FEATURES
* It meets the standards of both ISO2178
and ISO 2361 as well as DIN, ASTM
and BS. It can be used both in the
laboratory and in harsh field conditions.
* The F probes measure the thickness of
non-magnetic materials (e.g. paint,
plastic, porcelain enamel, copper, zinc,
aluminum , chrome etc.) on magnetic
materials (e.g. iron, nickel etc.) . often
used to measure the thickness of
galvanizing layer, lacquer layer,
porcelain enamel layer, phosphide
layer, copper tile, aluminum tile, some
alloy tile, paper etc.
* The N probes measure the thickness of
n o n - m a g n e t i c c o a t i n g s o n n o n -
m a g n e t i c m e t a l s . I t i s u s e d o n
anodizing, varnish, paint, enamel,
plastic coatings, powder, etc. applied
to aluminum, brass, non-magnetic
stainless steel, etc.
