3nh YT4200-P3 Coating Thickness Gauge (0~1250μm)

3nh YT4200-P3 Coating Thickness Gauge (0~1250μm)

3nh YT4200-P3 Coating Thickness Gauge (0~1250μm) is a handheld digital measurement device featuring a built-in probe (integrated probe). It utilizes the magnetic induction principle to measure the thickness of non-magnetic coatings (such as paint, plastic, enamel, chrome, zinc…) on magnetic metal substrates (Fe/Ferrous) like iron, steel, and cast iron.

Product Highlights of the YT4200-P3 Series

• Convenient Built-in Probe Design: Unlike the P7 series (separate probe), the YT4200-P3 integrates the probe directly into the bottom of the device. This design allows users to hold and press to measure with one hand quickly, making it extremely suitable for rapid inspection of a large volume of products on flat production lines.
• Non-destructive Measurement: Accurately determines the thickness of paint films or plating layers without causing scratches, peeling, or any damage to the product surface.
• High Sensitivity and Repeatability: The probe uses advanced magnetic induction technology, providing an almost instantaneous response time with high stability.
• Easy Calibration: The gauge supports fast Zero-point calibration and multi-point calibration using the included standard calibration foils, helping to compensate for errors when measuring on iron/steel surfaces with different roughness or magnetic characteristics.

Practical Applications

The device is an indispensable quality control (QC/QA) inspection tool in heavy industries and mechanical processing:

• Mechanical Manufacturing and Steel Structures: Measuring the thickness of anti-rust paint and powder coatings on workshop frames, seaports, and steel pipelines.
• Automotive Industry (Used and New Cars): Checking paint thickness on car bodies (steel substrates) to determine whether the vehicle has been touched up, repainted, or applied with body filler (bondo).
• Electroplating Industry: Checking the thickness of non-magnetic zinc plating, chrome plating, and nickel plating layers on iron and steel workpieces.
• Casting and Metal Processing: Monitoring the surface protective coating quality of machine parts.
