Probes for coating thickness measurements Coating Thickness Material Analysis Material Testing

High-Precision Probes The heart of any electromagnetic measurement system is the probe; the quality of its signal ultimately determines the overall quality of the metrological solution. The probe is a very complex system, which performs the conversion of the appropriate measuring method: In this case the coating thickness is transformed into an electrical signal (count rate, frequency, voltage) in order to display the value of the coating thickness in the instrument display. Solutions for individual measurement tasks We offer the ideal probe for each individual measurement task. FISCHER...

The extensive selection of FISCHER probes is as versatile as the measurement applications of our customers. After years of continuous development and innovation, the FISCHER probe program now encompasses some 100 probes designed to ensure optimal results for the widest range of measurement applications. Probe selection based on several criteria • Material combination of coating and base material • Thickness of coating and base material • Dimension of the measurement area • Shape of the specimen • Surface condition of the measurement area Call us. We are happy to consult you on the matter of...

Versatile Fields of Applications Measurement of the corrosion protection coating in plastics on steel pipes with the probe FKB10 Measuring of duplex coatings with the probe FDX13H Measurements of anodized coatings with the curvature-compensating probe FTD3.3 Automated measurement of the chrome coating on piston rods with the probe V2FGA06H Measurement of zinc powder coating with the two-pole probe V7FKB4 Measurement of auto body paint thickness using the Dual probe FD10

Support stands For precise and reproducible measurements on small parts, such as fasteners, stampings, sleeves etc. or parts with complex geometry a measurement stand is necessary, into which a probe can be clamped. The reproducible positioning of the probe on the specimen substantially improves the repeatability of the readings – reduction of the reading variation. Suitable for all probes. Standard scope of supply of the support stands • Various clamping devices for Fischer standard axial probes (A) • Even and V-table for small parts (B) • Stop device for repeatable specimen A positioning...
