HW-300PRO Car Paint Thickness Gauge and Digital Coating Thickness Meter

Inspect vehicle paintwork with more confidence before buying, detailing, or repairing a car. The HW-300PRO measures coating thickness without damaging the surface and automatically recognizes ferrous and non-ferrous metal bases. Its wide 0–2000 m range helps reveal variations that may indicate repainting, refinishing, or filler beneath the paint. A backlit LCD and simple handheld design make readings easy to view in workshops, garages, and outdoor locations.

Key Features

• Measures coatings from 0 to 2000 m
• 1 m resolution with stated accuracy of ±3% + 1 m
• Automatic Fe/NFe detection for steel and aluminum surfaces
• Displays results in m, mm, or mils
• Shows average, minimum, maximum, and reading count
• Supports zero and multi-point calibration
• Backlight, battery indicator, and automatic shutoff

Why Choose the HW-300PRO

Unlike basic magnetic testers, this automotive paint tester works on both ferrous and non-ferrous metal substrates. Its calibration controls and statistical readings provide more useful comparisons across several body panels.

Perfect For

Used-car inspections, automotive detailing, body shops, paintwork checks, manufacturing, metal processing, and coating quality control. This paint depth gauge can measure paint, enamel, chrome, and other suitable non-metallic coatings over metal.

How to Use

Calibrate the meter with the supplied reference materials, then place the probe flat and perpendicular to a clean surface. Take several readings across each panel and compare the results rather than relying on one measurement.

Product Note

Readings cannot prove accident history or independently identify body filler. The meter requires a compatible metal substrate and will not measure paint correctly on plastic, fiberglass, or carbon-fiber panels.

Inspect with Better Information

Add this metal coating gauge to your toolkit and make paint inspections quicker, clearer, and more consistent.
