SpecMetrix® In-line Coating Measurement Systems

Real-time, non-contact coating thickness control – right on your production line

SpecMetrix® In-line Systems deliver instant, ultra-precise coating thickness and film weight data during production – so you can cut waste, optimize process, speed up changeovers, and keep quality in spec across substrates and colors.

We are proud to offer SpecMetrix In-line coating measurement systems that can be easily integrated to your production lines for immediate quality control and process control benefit. All systems use our innovative, patented ROI/EXR technologies that provide you with non-contact, non-destructive and real-time thickness measurement data during the coating process over a diverse range of substrates. Designed for coil coaters, flexible packaging manufacturers, metal packaging producers and industrial coating operations, SpecMetrix® In-line Systems help production and quality teams monitor coating thickness continuously without interrupting production, reducing waste while maintaining consistent product quality.

Why manufacturers choose SpecMetrix In-line Coating Measurement Systems:

• Maintains Product Integrity: Non‑contact, non‑destructive readings preserve coating and substrate integrity.
• Versatile measurement capability: Can be used to measure wet or dry coatings across clear, colored and pigmented applications. Whether it be coated metal coils and flat sheets or films, foils and flexible packaging, we’ll have a system to meet your specifications.
• Configure to meet your needs: In-line systems allow for maximum flexibility and deliver continuous stream of more precise coating thickness data in real-time at 100+ measurements per second, enabling plants to reduce coating costs and optimize coating consumption.
• Signifcant material savings: By delivering precise, continuous thickness data, our technology helps manufacturers cut coating over‑application, minimize scrap, and improve overall material efficiency. It also accelerates plant setup, changeovers, and inspections – enhancing productivity across diverse industrial coating processes with either fixed‑probe or traversing system configurations.
• Control in real time: All coating measurements are captured in real-time and are displayed on the intuitive SpecMetrix touch screen interface – allowing operators and process teams to have streamline QA processes and make quality adjustments immediately. This enables manufacturers to identify process variation as it happens, helping prevent out-of-specification product before it leaves the production line.

Where SpecMetrix in-line Coating Measurement Systems are used

SpecMetrix® In-line Coating Measurement Systems are extremely versatile. No matter the substrate you are coating, we will likely have an in-line coating and layer thickness measurement solution to meet your wet or dry coating process control and quality assurance needs:

• Coil Coating Lines: Real‑time, absolute thickness data for primers, backers, top coats, and more – on aluminum, steel, tinplate, and coated or laminated coils.
• Flexible packaging & roll‑to‑roll (R2R): Measure wet or dry layers on films, foils, laminates, and converted products—single‑ or dual‑sided—without stopping the line. 
• Metal Packaging Lines: Measures wet or dry coating weight of applied lacquers and coatings on flat sheet production lines.

Our user‑friendly software captures all in‑process data, exporting to Excel® or connecting to plant networks for SPC analysis. Each run generates a permanent quality record, simplifying audits and resolving quality or claim inquiries. This provides production and quality teams with complete traceability and valuable process insights to support continuous improvement.

Flexible system configurations

Our application experts can recommend the ideal in‑line or offline measurement configuration for your production and QA needs – no matter how complex your process. Contact us to discuss the right solution for your coating measurement requirements.

How do you collect data through the system?

Our world-first technology allows you to gather real-time data when gathering thickness measurements for applied coatings – ultimately allowing you to make instant adjustments during the process.

What are the benefits of real-time data collection?

Gathering data in real-time allows you to significantly cut down on paint and material waste by making more accurate paint applications to your chosen substrate. Ultimately, allowing you to achieve significant cost savings. Real-time process visibility also helps reduce downtime, improve production efficiency and accelerate line changeovers.

Have other businesses saved money using our systems?

Our innovative technologies have allowed various customers to achieve the following:

• A 15% reduction in paint consumption after system implementation on just the primer and backer processes  
• A 20% overall cost savings for the business after system implementation on just the backer process  
• A reduction in cost of more than $50,000 per month after system implementation on just the primer process  

SpecMetrix technology also allowed one company to achieve annual savings of $2.4 million.
