15 Coating Thickness Probes for Common and Complex Applications For Thick Coatings For Thin Coatings For Hard to Reach areas For Curvatures For Edge Effect For Surface Roughness For Soft Coatings For Duplex Coatings For Underwater Measurement

to Reach areas For Curvatures For Edge Effect For Surface

16 Use the Correct Probe for the Measurement Task Selection Considerations Surface roughness Edge effects How close can you get to an edge with minimal effect on a measurement value? Coating material Coating thickness Substrate material Consult the vendor as required to be sure the probe choice is optimal for your needs

17 Use the Correct Probe for the Measurement Task Select a probe with the correct measurement range On aluminum and non-ferrous bases look for probes with automatic conductivity compensation Much less sensitive to differences in base materials Consider probes with curvature compensation Much less sensitive to part shape Select the probe tip to meet the job. Wide tip or dual tip probes on rough surfaces

sensitive to differences in base materials Consider probes with curvature compensation Much less
