Which
probe do I need for my application? What is my Coating/Substrate Combination?
The table
below will help you pick the right type of gauge, and establish whether
measurement is possible. There must be a physical difference between
the properties of the substrate and coating i.e. magnetic 'substrate'
with Non-magnetic 'coating' or conductive 'substrate' with Non-conductive
'coating'.
The list below shows common coating / substrate combinations. If you do not see your coating / substrate combination, please contact BAMR to discuss your particular requirement.

Note that
? combination have non-linear responses which can be handled by the
special calibration function.
Some stainless
steels should be regarded as Ferrous because of their composition, where
a customer is unsure a simple magnet test will help.
