HW-300 Car Paint Film Thickness Gauge 0-2000µm DFT Meter

HW-300 Automotive Paint Film Thickness Gauge – Precise Coating Measurement

The HW-300 Car Paint Film Thickness Gauge is a professional-grade, handheld DFT (Dry Film Thickness) meter designed for accurate, non-destructive measurement of coatings and paint layers on metal surfaces. Whether you're inspecting a used vehicle, working in a body shop, or conducting quality checks in a manufacturing environment, this compact tool delivers fast and reliable results across a wide measurement range of 0–2000 µm.

Using the dual principles of electromagnetic induction (FE) and eddy current effect (NFE), the HW-300 automatically detects the substrate type and switches measurement mode accordingly — measuring paint, enamel, chrome, and anodized coatings on ferrous (steel/iron) and non-ferrous (aluminum, copper) substrates with ease.

Made in Mainland China.

Frequently Asked Questions

Q: What surfaces can the HW-300 paint thickness gauge measure?

A: The HW-300 can measure coatings on both ferrous substrates (steel, iron) using electromagnetic induction and non-ferrous substrates (aluminum, copper) using the eddy current method. It automatically detects the substrate type, making it versatile for automotive paint, chrome, enamel, anodized layers, and industrial coatings.

Q: Does the HW-300 DFT meter come with batteries?

A: No, batteries are not included. The gauge requires 2 × 1.5V AAA batteries, which are widely available. The device features a built-in battery level indicator so you always know remaining charge.

Q: Is this thickness gauge suitable for checking used car paint at a dealership or auction?

A: Absolutely. The HW-300 is a popular tool for pre-purchase vehicle inspections. Its 0–2000 µm range covers factory and repainted layers, helping you quickly identify areas that may have been repaired or repainted — a key step in assessing a vehicle's condition.

Q: How accurate is the HW-300 coating thickness gauge?

A: The HW-300 delivers a measurement accuracy of ±(3% + 1 µm) with a resolution of 1 µm (0.01 mm). This level of precision is well-suited for both automotive inspections and industrial quality control applications.
