The P-11-S-AL Paint Depth Gauge from Blue Technology measures paint coating thickness from 0 to 1990 µm and automatically identifies whether the substrate is steel, galvanised steel or aluminium. This means the user does not need to manually switch measurement mode between each measuring point, saving time when checking an entire body shell.

The spring-mounted ball probe sits on an 80 cm long cable, giving access to wheel arches, door sills and other hard-to-reach parts of the vehicle. A built-in LED torch makes work easier in poorly lit environments, such as workshop pits or during evening shifts at a detailing studio. See more measuring instruments for car care in our range.

The audible signals make it possible to interpret the result without constantly looking at the display: one short signal indicates original paint, two short signals indicate two layers of paint, and one long signal warns of filler beneath the paintwork. This makes the gauge particularly useful when assessing used vehicles.

When Does the Paint Depth Gauge Make the Most Sense?

The Paint Depth Gauge proves its worth during inspection of used vehicles, where irregular coating thickness can reveal previous collision damage or repainted areas. With a measurement range of 0–1990 µm and a resolution of 10 µm, the instrument even captures minor thickness variations that are difficult to see with the naked eye. Automatic substrate detection makes it possible to switch between steel, galvanised steel and aluminium without interrupting the workflow.

Applications for the Paint Depth Gauge

• Inspection and valuation of used cars
• Quality control after paint repair
• Damage assessment for insurance claims
• Pre-purchase checks for private buyers and car dealers
• Ongoing quality assurance in detailing workshops

Frequently Asked Questions (FAQ)

Does the P-11-S-AL Paint Depth Gauge from Blue Technology work on plastic parts?

No, the P-11-S-AL Paint Depth Gauge from Blue Technology is designed for steel, galvanised steel and aluminium. Plastic, carbon fibre and other non-metallic substrates cannot be measured accurately with this instrument, as it relies on magnetic and electromagnetic induction. See more products from Blue Technology for other vehicle-related needs.

How long do the batteries last in the P-11-S-AL Paint Depth Gauge from Blue Technology?

The P-11-S-AL Paint Depth Gauge from Blue Technology runs on two 1.5V AA batteries and manages up to 100 hours of continuous use before the batteries need replacing. This makes the instrument suitable for daily use by detailers and detailing workshops without frequent battery changes.

What sets the P-11-S-AL Paint Depth Gauge from Blue Technology apart from other paint depth gauges on the market?

The P-11-S-AL Paint Depth Gauge from Blue Technology combines automatic substrate detection with a spring-mounted ball probe on an 80 cm cable, giving access to curved and hard-to-reach surfaces without having to switch measurement mode manually. The built-in audible signals, which distinguish between original paint, double layers and filler, also allow for quicker interpretation compared with gauges that only display numerical values.
