3nh YT4500-P1 Coating Thickness Gauge (0~1250μm)

3nh YT4500-P1 Coating Thickness Gauge (0~1250μm)

3nh YT4500-P1 Coating Thickness Gauge (measuring range 0~1250μm) is a specialized measurement device featuring a neat, integrated probe (Integral Probe) design from 3nh. The device utilizes both magnetic induction (Fe) and eddy current (NFe) principles, enabling fast, accurate, and non-destructive testing of coating, plating, and film thickness on metal substrates.

Unlike the P3 series (which uses a separate probe via a cable), the 3nh YT4500-P1 series is optimized for one-handed measurements, allowing users to operate quickly and stably on flat surfaces or workpieces with unobstructed spaces.

🌟 Product Highlights

• Integral Probe: The monoblock design makes the device extremely compact, pocket-sized, easy to grip, and allows for quick one-handed measurements without the hassle of cables.
• Automatic Dual Measurement Mode (Fe/NFe): The gauge automatically recognizes and switches the measurement algorithm upon contacting the substrate.
• Fe Mode (Magnetic Induction): Measures non-magnetic coatings (paint, plastic, enamel, chrome, zinc, etc.) on magnetic metal substrates such as iron and steel.
• NFe Mode (Eddy Current): Measures insulating coatings (paint, anodizing, plastics, etc.) on non-ferrous metal substrates such as aluminum, copper, stainless steel, and brass.
• Intuitive Interface & Multi-mode: Supports a clear display screen, measurement data statistics (Average, Max, Min, Standard Deviation), and a flexible zero-point/multi-point calibration system to ensure the highest accuracy.
• High Resolution: Reaches up to 0.1μm within the thin measuring range (under 100μm), helping to strictly control the quality of powder coatings or electronic plating layers.
