86226 High Precision Coating Thickness Gauge
Ideal for Measuring Coating Thickness on Flat Surfaces
Gravity-based measurement ensures stable positioning
Dual-screen display for easy readability
1-5 point calibration for complex applications
This high-precision coating thickness gauge is designed to measure non-magnetic coatings—such as paint, varnish, enamel, chrome, and galvanizing—on ferromagnetic metal substrates like steel or iron. It also accurately measures non-conductive coatings—including paint, anodized layers, and ceramics—on non-magnetic metals such as copper, aluminum, die-cast zinc, and brass. The gauge automatically detects the substrate type and switches modes accordingly, making it ideal for use in manufacturing, metal processing, chemical industries, quality inspection, and more.

Features
Gravity-Based Measurement for Stable Readings
The device utilizes its own weight to maintain consistent pressure on the probe during measurement. This helps minimize human error and ensures reliable, repeatable results.
Dual-Screen Display for Enhanced Visibility
Equipped with both front and top display screens, the gauge allows users to view thickness readings from multiple angles, improving efficiency and ease of use.


Multi-Point Calibration for Complex Scenarios
Supports zero calibration and 1–5 point calibration using dedicated zero plates and standard sheets. This ensures accurate readings, even in challenging testing environments.
Dual-Mode Probe for Ferrous and Non-Ferrous Metals
The smart probe automatically identifies whether the substrate is ferrous or non-ferrous, adjusting accordingly to provide precise coating thickness measurements across a variety of metals.
