The HW-300 Paint Thickness Gauge is a professional coating thickness meter designed for accurate assessment of a car's body condition. The device allows for professional inspection to detect hidden repair work, non-factory paint, and evaluate the overall condition of the paintwork. It is an indispensable tool when checking a car before purchase, as it helps to find traces of repair after accidents, even minor collisions, which can be grounds for price reduction or reconsideration of the purchase.
The device works with metallic (Fe) and aluminum (NFe) surfaces, automatically detecting the material type. This allows it to be used for inspecting bodies made of various materials. For the most accurate results, the device must be held strictly perpendicular to the measurement surface.
Main features and characteristics:
- Automatic material detection: metal (Fe) / aluminum, copper (NFe).
- Thickness measurement in three units: millimeters (mm), microns (µm), and mils (mil). Switching between units is done with a button.
- Built-in display backlight for working in low-light conditions.
- Display of the number of measurements taken since the device was turned on.
- Automatic shut-off when not in use to save battery power.
- Compact dimensions: 110x52x25 mm, making the device convenient for storage and carrying.
Package includes:
- HW-300 Paint Thickness Gauge.
- Metal calibration plate.
- Test plates for checking device accuracy.
- User manual (batteries not included).
IMPORTANT: Before first use, the device must be calibrated. Detailed instructions for calibration and use of the HW-300 can be found on our website.

Operation and calibration:
After turning on, the device performs an initial calibration to "0". For accurate measurements, it is recommended to periodically check the calibration using the included metal calibration plate.
The measurement process is simple: place the device perpendicular to the surface, press the measuring head, and the display will show the paint thickness in the selected units. The device counts each measurement, which is convenient for keeping inspection statistics.

The HW-300 Paint Thickness Gauge allows quick and accurate checking of paint condition.

Initial device calibration is the key to accurate measurements.
Who is the HW-300 for?
- For used car buyers: objectively assess the body condition before a deal.
- For auto repair shops and services: control the quality of painting and repair work.
- For insurance companies and appraisers: document the vehicle's condition.
- For car enthusiasts: independently monitor the condition of your car's paintwork.
