This device measures the thickness of the paint/coating on car bodies, helping you determine:
-
If a vehicle has been repainted
-
Where body repairs or filler (putty) may have been applied
-
Whether coatings are within factory specs
It works on both ferrous (steel) and non-ferrous (aluminium) surfaces using magnetic induction (Hall effect) and eddy-current principles.
🔍 Key Features
🎨 Multi-Substrate Detection
Automatically detects:
-
Ferrous (Fe) steel body
-
Aluminium (Al)
-
Galvanised iron
-
Non-metallic surfaces like plastics
This helps to quickly distinguish different parts of a car and get meaningful thickness readings.
🔄 Three-Color Backlight & Indicator System
The built-in screen and button backlight change colour based on paint thickness:
-
White – thin paint (typically original)
-
Yellow – mid-range thickness
-
Red – thick paint or ferrous putty detected
This provides an instant, visual cue of possible repainting or filler presence.
📱 Bluetooth & Mobile App Support
-
Built-in Bluetooth lets you connect to a mobile app to generate detailed inspection reports, save data, and share results.
-
Works with compatible Android & iOS devices for easier data management.
🔋 Rechargeable & User-Friendly
-
Powered by a rechargeable lithium battery with USB-C charging for convenience.
-
Rotatable display screen makes reading easier in tricky angles.
-
Lightweight and compact for handheld use.

🛠 Why It’s Useful
-
For used-car buyers: check if paint thickness is consistent across the vehicle — variations can indicate repairs.
-
For body shops & detailers: verify even application of repaint or coatings.
-
For inspectors & dealers: generate digital inspection reports with the Bluetooth app.
