AUTOOL TG501 Fe/NFe Automotive Coating Thickness Gauge

Map Paint Thickness Across Steel and Aluminum Panels

The AUTOOL TG501 recognizes ferrous and non-ferrous substrates automatically and stores readings so you can compare coating thickness panel by panel. It works on metal only, not on plastic or composite parts.

Hauptmerkmale

Automatic Fe and NFe Recognition

Switches between magnetic induction on steel and eddy current on aluminum and other non-ferrous metals, so mixed-metal bodies need no manual switching.
Stored Readings for Comparison

Save readings from comparable points to review them across panels or workpieces.
Automatic Screen Rotation

The display turns with the gauge, keeping the value readable at angled or confined measuring points.
Unit Switching

Change units to match the reference standard or inspection record.
Included Check Plates

Metal substrates and thickness films for zero and reference checks before measuring.
Auto Power-Off

Turns off after about two minutes without operation to save battery power.

Anwendung

Inspect the surfaceConfirm the metal substrate type, enough area and curvature, and a clean, dry measuring point.
Check the gaugeRun the zero and reference check with the supplied substrates and films.
Map comparable pointsHold the probe perpendicular and steady, and measure several points on each panel rather than one spot.
Record contextNote panel, position, substrate, unit and any edge, curvature, contamination or repair context.
Investigate the patternRepeat unexpected readings. Thickness alone does not prove accident damage; combine it with a full body and mechanical inspection.

Good to Know

Caution

Plastic and composite panels cannot be measured with this gauge; they need another method.
Edges, tight curves, small areas, dirt and unstable contact can affect results.
