Coating Thickness Gauge – QualiCTG™ V

Coating Thickness Gauge – QualiCTG™ V measures non-magnetic coatings like paint, varnish, enamel, chrome, and galvanizing on ferromagnetic metals such as steel or iron. It also measures non-conductive coatings like paint, anodized layers, or ceramic on non-magnetic metals, including copper, aluminum, die-cast zinc, and brass. The gauge automatically detects the substrate and switches measurement modes accordingly. It is commonly used in manufacturing, metalworking, chemical processing, quality inspection, and related industries.

Coating Thickness Gauge – QualiCTG™ V Features

Gravity-Based Measurement for Stable Positioning
The device uses its own weight to apply consistent pressure, ensuring uniform probe contact during each measurement. This minimizes operator influence, improves repeatability, and delivers more stable, reliable readings. Coating Thickness Gauge – QualiCTG-V

Dual-Screen Design for Easy Reading
The front and top display screens allow for quick, clear viewing of thickness measurements from any angle, enhancing efficiency and ease of use.
