The HW-300PRO Digital Car Paint Coating Thickness Gauge is a precision tool designed for non-destructive measurement of coatings on metal surfaces. It is primarily used to detect paint thickness on automobiles, helping identify hidden repairs, body filler (Bondo), or non-factory paint jobs before purchasing a used vehicle.
Key Specifications & Features
Measurement Range: 0 to 2000
m (0 to 2 mm).
Accuracy:
Resolution: High precision at
Dual-Principle Probe: Automatically identifies the substrate type—Fe (ferrous/magnetic metals like steel/iron) or NFe (non-ferrous metals like aluminum/copper).
Smart Statistical Display: Can simultaneously record and display Average (AVG), Maximum (MAX), Minimum (MIN), and the Number (NUM) of readings taken.
Backlight LCD: Features a high-definition screen with a backlight for easy reading in low-light conditions.
Power: Operates on 2 x 1.5V AAA batteries (typically not included) and features an automatic shutdown function to preserve battery life.
How to Use the HW-300PRO
Preparation: Ensure the car’s surface is clean and dry; dirt can cause inaccurate readings.
Calibration: Before first use or when changing substrates, perform a Zero Calibration by placing the probe on an uncoated metal base and pressing the ZERO CAL button until it reads “0”.
Measurement: Place the probe vertically and firmly against the paint surface. The device will beep and display the thickness reading in seconds.
Analysis: Take multiple readings across different panels (e.g., hood vs. door) to check for consistency. Significant deviations often indicate a prior repair or accident history.
Why Professionals Use It
Non-Destructive: Measures paint depth without scratching or damaging the finish.
Portable Design: Lightweight (approx. 109g) and compact for easy use during on-site inspections or at auctions.
Versatility: Useful beyond automotive, including manufacturing, powder coating, and metal processing.
