3nh YT4500-P3 Coating Thickness Gauge (0~1250μm)

3nh YT4500-P3 Coating Thickness Gauge (0~1250μm)

3nh YT4500-P3 Coating Thickness Gauge (measuring range 0~1250μm) is a high-end, specialized measurement device featuring a separate probe (Split structure) for flexible operation at multiple angles and narrow spaces. The device combines both magnetic induction (Fe) and eddy current (NFe) measurement principles, allowing non-destructive testing of coating thickness on both magnetic and non-magnetic metal substrates.

🌟 Product Highlights

Automatic substrate recognition: The gauge automatically identifies whether the substrate is magnetic metal (Fe – such as iron, steel) or non-magnetic metal (NFe – such as aluminum, copper, stainless steel) to automatically switch to the appropriate measurement mode.

Flexible separate probe (Split Structure): The probe design connected via a cable allows users to easily access narrow gaps, curved surfaces, or hidden corners compared to integrated probe models.

International standards: The device fully complies with strict measurement standards such as ISO 2178, ISO 2360, GB/T 4956, GB/T 4957, and ASTM B499.

High accuracy: Super-fine resolution reaches 0.1μm when measuring thin coatings (under 100μm), providing maximum support for surface quality inspection work.
