Coatmaster Flex unique non-contact coating thickness gauge

Coatmaster Flex is a revolutionary handheld coating thickness gauge that uses the patented ATO (Acoustic Thickness Optical) technology.

Unlike traditional measuring instruments, Coatmaster Flex allows measuring the thickness of a wet coating immediately after application – contactless and non-destructive, without damaging the coating.

The device is ideally suited for use on metal, paper, rubber, ceramic, glass and plastic surfaces.

The Coatmaster AT and INLINE models additionally measure on firmer wood surfaces.

Why choose

Coatmaster Flex?

On production lines, coating thickness control is critical – too thick a layer wastes material and money, too thin does not provide sufficient protection.

Coatmaster Flex solves this problem in real time: you immediately know whether the coating meets the standard, without having to wait for it to dry.

Key benefits

Instant measurement on a wet surface – do not wait for drying, measure immediately after painting and adjust the process in real time Up to 30% material savings – apply exactly the right amount of paint, not more just in case Smart process control – connect the device to an ERP system or via a browser and receive real-time data directly into the control system Universal compatibility – works with metal, paper, rubber, ceramic, glass and plastic; measures all colour shades including white surfaces Safe and contactless – does not damage the coating, does not create hazardous emissions Moving products – can also measure products on a moving production line Wide tilt angle tolerance ±70° – works even on parts with more complex geometry How does it work?

The ATO technology of Coatmaster Flex combines the acoustic and optical measurement principle.

The device emits a short sound signal towards the surface and optically analyses the coating's response – everything takes place contactless at a measuring distance of 2–15 cm from the part.

Measurement takes only from 20 milliseconds, which makes the device suitable for use even on high-speed lines.

Who uses Coatmaster Flex?

The device is especially popular in the woodworking industry, metalworking, automotive body industry and paper production, where a high-quality and uniform coating is an integral part of product quality.

Coatmaster Flex is used by both small businesses and large manufacturing companies that want to optimise material costs and ensure stable product quality.

FAQ – frequently asked questions Does Coatmaster Flex also measure dried surfaces?

Yes, the device measures dried/cured surfaces in the range of 1–1000 μm and wet coating thickness of 1–400 μm.

On which materials can it measure?

Coatmaster Flex works on metal, paper, rubber, ceramic, glass and plastic surfaces.

The device measures all colour shades, including white surfaces.

Can the device also measure on a moving production line?

Yes, Coatmaster Flex is capable of measuring on moving products.

With a measuring time from 20 milliseconds, the device is also suitable for fast production lines.

How does the data move into the system?

Measurement results are transferred in real time to the ERP system or are accessible via a browser – easy integration into the existing production environment.

From how far can it measure?

The optimal measuring distance from the part is 2–15 cm and the device tolerates a tilt angle of up to ±70°, which provides great flexibility in measuring various parts.

Why choose

Coatmaster Flex instead of other coating thickness gauges?

Most traditional coating thickness gauges require the coating to be dry before measurement.

Coatmaster Flex allows measuring immediately after application, which saves production time and reduces the occurrence of rejects.

In addition, the device is contactless – this means it does not damage the surface or require cleaning activities between measurements.

Coatmaster Flex is a handheld contactless coating thickness gauge that measures coating thickness immediately after application – even when wet!

The ATO technology ensures an accurate result from 20 milliseconds, with a measuring distance of 2–15 cm.

Suitable for metal, paper, rubber, ceramic, glass and plastic.

Real-time data via the ERP system – save up to 30% on paint material.
