The HW-300PRO automatically detects whether the substrate is ferrous (steel\/iron) or non-ferrous (aluminum, copper) using its built-in FE\/NFE dual-mode sensor — no manual mode switching needed. It accurately measures paint, enamel, chrome, and anodized coatings on both types of surfaces.\u003c\/p\u003e\n\u003ch4\u003eQ: Do batteries come included with the HW-300PRO paint film thickness tester?\u003c\/h4\u003e\n\u003cp\u003eA: No, batteries are not included. The gauge is powered by 2 × 1.5V AAA batteries, which are widely available and sold separately.
