Brought to you by SpecMetrix, our specialist coating brand, dedicated to innovative coating thickness measurement technologies.
The SpecMetrix® Lab DFTQA System delivers non-contact, non-destructive, real-time absolute measurement of dry film thickness for primers, base coats, top coats and clear or pigmented coatings. It is used by coil coating lines, coil pre-treatment operations, metal coil coaters and appliance panel coaters to verify coating thickness in the QA lab or R&D center, giving accurate data across the full sample area rather than isolated spot checks that miss variation.
Catch coating variation before it reaches the customer. Absolute thickness data across the full sample area, not isolated spot checks, means QA teams catch under- and over-application before it becomes a customer claim.
Test the full range of coil coatings without recalibrating. From clear coats to heavily pigmented top coats, over aluminum, steel, tinplate, cold-rolled steel or Galvalume, the system reads accurately without recalibrating for color or substrate change.
Cut material waste and rework in the QA lab. Non-destructive testing preserves the sample and reduces the scrap, rework labor and repeat testing that damaging spot-check methods create.
Broad range of coil coatings
Dual optical packages
A single system configuration includes two optical packages as standard, so operators can take faster primer and top coat measurements without swapping hardware between runs.
Ruggedized optical interference technology
The system uses ruggedized optical interference (ROI), the non-destructive measurement method defined in ASTM D8331. Measurement accuracy is independent of operator skill, giving repeatable and reproducible results without recalibration for different colors or substrates.
Powerful SpecMetrix Software
The user-friendly SpecMetrix software package stores all measurement data to Excel® or interfaces with plant networks for SPC analysis. A built-in Recipe Assistant helps operators create and edit coating formulas and recipes.
SpecMetrix coating thickness technology has helped coil coating customers reduce material waste and cut costs. Reported results include:
One customer achieved annual savings of more than $2.4 million after adopting SpecMetrix coating measurement technology – see the full case study.
With SpecMetrix’s precise and innovative optical technology, users can obtain detailed dry film thickness measurement data for their coatings – all through non-contact and non-destructive means.
The technology is extremely precise and gives users a true picture of their coatings. The DFTQA allows users to obtain accurate coating layer thickness and DFT measurements over the sample area, instead of isolated measurement spots that are not representative of the whole coating distribution.
In addition, a single system configuration can include dual optical packages, so that users can obtain faster primer and top coat measurements. Our patented, exclusive optical technology is highly advanced and relied upon throughout coating industries.

Inefficient, waste‑heavy coating processes → Adopted SpecMetrix innovative coating thickness testing technology → Delivered major cost savings and strong ROI ✓
The customer’s high‑volume coil coating line struggled with overcoating, manual checks, test strip interruptions, and inconsistent quality. These inefficiencies created significant material waste, labor costs, and production downtime across a 24/7 operation producing more than 200,000 tons annually. Even small process variations multiplied into major financial losses.
SpecMetrix’s in‑line measurement technology delivered real‑time, highly accurate coating control that eliminated test strips, reduced manual adjustments, and stabilized production. The system provided continuous verification of coating thickness, removing guesswork and enabling operators to maintain precision at full line speed. This transformed the process from reactive and labor‑intensive to automated, consistent, and data‑driven.
The customer achieved more than $2.4 million in annual savings, including $1.5 million in reduced coating usage and $600,000 from eliminating test strips. Additional gains came from lower labor demands, reduced spoilage, and fewer customer claims. The investment paid for itself in under two months, redefining operational efficiency and long‑term profitability.
