86225+F500 Plating Thickness Gauge
Ideal for Measuring Ultra-Thin Coatings Below 10μm
Utilizes advanced digital oscillation technology
Supports continuous measurement
Offers 1 to 5-point calibration options
The 86225+F500 is a high-precision plating thickness gauge featuring a separate host and probe design. It includes the 86225+F500 multi-probe coating thickness gauge host and the F500 probe.This instrument is specifically designed for measuring non-magnetic coatings—such as copper, zinc, tin, and chromium—on ferromagnetic metal substrates like iron. The 86225+F500 delivers exceptional measurement accuracy and repeatability, making it ideal for detecting ultra-thin coatings under 10μm.Widely used in metal processing, hardware manufacturing, and similar industries, it’s especially well-suited for testing small components thanks to its minimum measurement area diameter of just 7 mm.

1. The difference between 86225 and other coating thickness gauges
Compared with several other coating thickness gauges, 86225 has higher measurement accuracy and data repeatability. With a special test fixture, it can be used to accurately measure ultra-thin coatings below 10μm, small size and special-shaped workpieces. It supports zero adjustment and multi-point calibration. The measurement results can be more accurate after calibration through standard films or uncoated workpieces.
