Coating Thickness Gauges

The TASI TA521A Coating Thickness Gauge is a professional portable non-destructive testing instrument, also known as a paint thickness gauge, coating thickness tester, film thickness meter, dry film thickness gauge (DFT gauge), and coating measurement instrument. Utilizing dual measurement technologies of magnetic induction and eddy current, the instrument provides fast and accurate measurement of non-magnetic coatings and non-conductive layers applied on metal substrates, including paint coatings, powder coatings, plastic coatings, anti-corrosion coatings, electroplated layers, and surface treatment coatings. The TA521A automatically identifies different substrate materials, including ferrous (Fe), non-ferrous (NFe), and galvanized steel (Fe+Zn), and automatically selects the appropriate measurement method without manual switching. Equipped with a high-resolution 4-digit digital display and 180° automatic screen rotation, the gauge ensures clear readings from different viewing angles and is suitable for measurements on complex structures, narrow spaces, and irregular workpieces. It supports μm, mm, and mil measurement units to meet various international inspection standards. With its compact design, reliable accuracy, and convenient operation, the TA521A coating thickness tester is widely used in automotive manufacturing, used car paint inspection, vehicle appraisal, corrosion protection engineering, steel structure maintenance, bridge inspection, shipbuilding, pipeline anti-corrosion testing, electroplating industries, powder coating production, metal fabrication, machinery maintenance, industrial quality control, and third-party inspection services. The TA521A provides an efficient solution for coating quality inspection, corrosion protection evaluation, production line quality control, and field testing applications. It helps users verify coating thickness consistency, improve surface treatment quality, and ensure long-term durability of industrial products and metal structures.
