Paint Thickness Tester — Colour Micron Scale, Magnetic Tip, 20 µm Accuracy What it does Measures paint, varnish and filler thickness on steel and galvanised steel surfaces using a colour-coded micron scale. Detects paint layers invisible to the naked eye so you can quickly determine whether a vehicle has been repainted or repaired. Key benefits Fast, non-destructive checks: instant thickness reading with the tester tip and magnetic contact—no sanding or scraping required. Reliable detection: helps identify previous bodywork, excessive filler, or uneven coatings that may indicate prior repairs. Practical access: magnetic tip adheres to curved and hard-to-reach areas, making inspections on door frames, wheel arches and body panels easier. Main features Colour scale in microns for clear, visual thickness interpretation. Stated accuracy of 20 microns for consistent, repeatable readings. Magnetic tip designed to contact and hold to metal surfaces during measurement. Designed specifically for use on steel and galvanised steel substrates. How it works Place the magnetic tip of the tester against the clean, dust-free surface to be tested. Read the coating thickness from the colour-coded micron scale. The tip measures the combined thickness of varnish, paint and filler where present. Compatibility and performance Intended for vehicle inspection on steel and galvanised steel panels. Measures multi-layer coatings (varnish, paint, filler) and highlights variations that may indicate repainting or repairs. Accuracy specification: 20 microns. Practical use scenarios Buying a used car: quickly scan panels to confirm factory finish or find areas that were repainted or repaired. Auto repair and body shops: verify thickness of applied paint and filler to ensure consistent application and identify problem areas. Insurance and vehicle inspection: document coating variations and suspected previous repairs during assessments. Usage notes and precautions Surface must be clean and free of dust, dirt and loose material for accurate readings. Designed for ferrous substrates (steel and galvanised steel); not specified for non-ferrous metals or plastic panels. Use steady contact between the magnetic tip and the tested surface for the most reliable measurement. Why customers choose this tester Simple, visual micron scale and a magnetic tip that holds to curved panels deliver practical, repeatable inspections without destructive testing. Clear focus on vehicle panels made of steel and galvanised steel with an accuracy level suitable for routine checks and pre-purchase inspections.
