The P-13-S-AL Paint Depth Gauge from Blue Technology measures paint layers on steel, galvanised steel and aluminium with a resolution down to 1 µm. The 80 cm ball probe with pressure cable makes it possible to reach curved body panels and tight spaces without compromising measurement accuracy. Automatic substrate recognition means the gauge identifies the material itself before the measurement begins.

The three-colour backlit display shows immediately whether the surface has original paint, two layers of paint, or filler, which speeds up assessment during reconditioning and damage inspection. A built-in audio guide system complements the visual information with signals for each condition. Anyone looking for more measuring instruments for car care will find similar tools in our range.

With sixteen operating modes, a built-in LED torch and a battery life of up to 50 hours, the tool is built for daily use in workshop environments.

What sets the Blue Technology Paint Depth Gauge apart?

The gauge stands out through its combination of automatic substrate recognition, a three-colour display and audio guide, which makes the results easy to interpret without having to recalculate numerical values manually. Sixteen operating modes allow the measurement to be adapted to different tasks, from a quick check to detailed documentation.

A wide temperature range from -20°C to 40°C means the gauge works all year round, whether the work takes place indoors in a reconditioning workshop or outdoors during an inspection.

Where the Blue Technology Paint Depth Gauge performs best

• During used vehicle inspection to detect filler or repainting
• During damage assessment after a collision or paint damage
• In reconditioning workshops ahead of vehicle sale
• During quality control after painting at a workshop
• When purchasing used vehicles for detailed bodywork inspection

Frequently Asked Questions (FAQ)

Does the Blue Technology P-13-S-AL Paint Depth Gauge work on non-metallic surfaces?

No, the Blue Technology P-13-S-AL Paint Depth Gauge is designed specifically for steel, galvanised steel and aluminium. It is not suitable for plastic, carbon fibre or other non-metallic materials, as the measuring principle relies on magnetic and electromagnetic induction in metallic substrates.

How long does the battery last in the Blue Technology P-13-S-AL Paint Depth Gauge?

The Blue Technology P-13-S-AL Paint Depth Gauge is powered by two 1.5V LR3 batteries and manages up to 50 hours of continuous operation before the batteries need replacing. Automatic power-off after two minutes of inactivity further extends battery life, making the gauge suitable for longer working sessions in reconditioning workshops.

What sets the Blue Technology P-13-S-AL Paint Depth Gauge apart from traditional magnetic thickness gauges?

The Blue Technology P-13-S-AL Paint Depth Gauge combines automatic substrate recognition with a three-colour display and audio guide system, while many traditional magnetic gauges only show a numerical value without visual interpretation. The flexible 80 cm ball probe also provides access to convex and concave surfaces that are difficult to reach with rigid measuring tips.
