The paint film instrument is a professional tool used for inspecting automotive paint thickness. It has a range of features that enhance its functionality. Firstly, it automatically identifies the type of body material, whether it's iron or aluminum or non-metal. Additionally, it utilizes an intelligent identification algorithm, which enables it to detect accident cars that have been refined with metallic putty. Furthermore, it can automatically identify galvanized-iron high-grade anti-corrosion bodies. The instrument is equipped with a high-definition LCD screen and an ultra-low temperature LCD screen, allowing it to be used in strong light conditions and extreme temperatures as low as -40°C. The dual-screen design ensures that users can quickly read the measurements from any angle while inspecting the car.


  • Quick detection of metallic putty
  • Automatic identify non-metal car bodies, ferrous putty layers, and galvanized iron
  • Dual display design for real-time viewing of test data from different angles
  • Fast response time
  • High-quality Ruby probe with advanced digital probe technology
  • Switchable thickness measurement unit (μm / mil)
  • Zero adjustment and no calibration is needed
  • Single button operation
  • Real-time quick measurement
  • Wear-proof ruby probe tip for long-term use
  • Three measurement mode settings: Ferrous substrate measurement (Fe), Aluminum substrate measurement (Al), and Auto identification (Fe/Al)
  • Can measure the non-magnetic coating thickness on metal substrates and non-conductive coating thickness on non-magnetic metal substrates.
  • Non-slip groove design for relaxed time grip
  • A different color backlight according to the measured thickness:
    • White backlight: The measured paint thickness is between 30~170μm;
    • Yellow backlight: The measured paint thickness is between 170~350μm or <30μm;
    • Red backlight: The measured paint thickness is >350μm.
  • Stored up to 9 sets of historical data
  • Equipped with built-in Bluetooth communication, which can be connected to the gauge through the mobile app
