HW-300S Paint Thickness Gauge

Paint Thickness Gauge HW-300S is a professional digital coating thickness gauge designed for accurate assessment of automotive body condition. The device allows detecting hidden repairs, non-factory paint, and evaluating overall surface condition before purchasing a vehicle, conducting appraisals, or performing repairs.

The device performs non-destructive testing of coating thickness on metal, aluminum, and copper surfaces. Automatic base material detection enables precise measurement of paint, putty, or primer layers without preliminary settings. The device is particularly useful for auto experts, appraisers, body shop technicians, and regular car owners wanting to check a vehicle's history.

Calibration and User Manual

Primary application — detection of accident consequences, repaints, local body repairs. Documenting repair evidence allows reasonable price reduction when purchasing a car or avoiding dishonest deals. The device helps assess the scale and quality of previous repairs, which is critically important when choosing a used vehicle.

For maximum accuracy, the device must be held strictly perpendicular to the surface during measurement. The ergonomic body provides comfortable grip, while intuitive interface makes operation easy even for beginners.

The device automatically detects the material under the coating — ferrous metal, aluminum, or copper — eliminating measurement errors on different surface types.

Measurements are performed in three units: millimeters (mm), microns (μm), and mils (mil). Switching between units is done with a single button. Built-in display backlight enables comfortable work in low-light conditions — in garages, dark streets, or service areas.

Key features of Paint Thickness Gauge HW-300S:

• Automatic base material detection (Fe/Al/Cu)
• High measurement accuracy
• Ergonomic design and comfortable grip
• Display backlight for dark environments
• Non-destructive testing method
• One-click calibration
• Energy-efficient operation

The package includes calibration plates for quick verification and device setup. Batteries are not included — requires 2 AAA 1.5V batteries. Vertical display orientation facilitates easy reading during measurements.

How does Paint Thickness Gauge HW-300S work? The device uses electromagnetic measurement principle for ferromagnetic materials (iron, steel) and eddy current method for non-ferrous metals (aluminum, copper). The sensor generates an electromagnetic field that interacts with the metal substrate, and the processor analyzes changes to calculate coating thickness.

Application areas:

1. Used car inspection before purchase
2. Body repair quality control in auto shops
3. Coating condition assessment for insurance
4. Technical examination after accidents
5. Production coating thickness control
6. Anti-corrosion coating inspection

Advantages of HW-300S model compared to alternatives:

• Automatic material recognition — no manual mode switching required
• High accuracy ±3% — professional measurement level
• Ergonomic body — comfortable for extended use
• Display backlight — usable in poor lighting
• Easy calibration — takes seconds
• Reliable construction — resistant to drops and vibrations

Typical coating thickness values:

• Factory coating (original): 80–180 μm
• Repaint (one layer): +50–100 μm to original
• Local repair with putty: from 200 μm and above
• Primer: 30–80 μm
• Clear coat: 30–50 μm

The HW-300S device comes in sturdy packaging with calibration plates and detailed English manual. This is the optimal choice for professionals and private users who value accuracy, reliability, and ease of use.
