How to Use the PosiTector 200 to Measure 10:02
Learn how the PosiTector 200 Ultrasonic Coating Thickness Gage non-destructively measures coating thickness over wood, concrete, plastic, and more using proven ultrasound technology.
Advanced Ultrasonic Measurement for Non-Metallic Surfaces
The PosiTector 200 is a professional-grade ultrasonic coating thickness gauge designed specifically for non-metal substrates such as wood, concrete, fiberglass, plastics, and composites. Unlike magnetic or eddy-current gauges, which only work on metals, the PosiTector 200 uses advanced ultrasonic pulse technology to deliver fast, accurate, and non-destructive coating thickness measurements.
Available in both Standard and Advanced models, it provides the flexibility to measure total coating thickness or, in advanced mode, even identify and measure up to three individual coating layers. This makes it invaluable for industries such as construction, flooring, marine, composites, restoration, and furniture finishing.
As the official UK distributor and DeFelsko Authorised Service Centre (DASC), DFT Instruments ensures every PosiTector 200 is supplied with full calibration, certification, and local service support — giving you the confidence that every reading is accurate, traceable, and backed by experts.

Why Testing Matters
- Measure Where Other Gauges Can’t
Traditional dry film thickness gauges work only on metals. The PosiTector 200 fills the gap by providing reliable, non-destructive measurements on non-metal substrates such as wood, concrete, fiberglass, composites, and plastics. - Protect Against Failure
Correct coating thickness is essential for protecting surfaces against wear, corrosion, moisture ingress, and UV degradation. Ultrasonic measurement helps verify that protective layers are applied correctly, reducing costly defects and rework. - Verify Multi-Coat Systems
Many real-world applications involve multiple layers — primers, barrier coats, and topcoats. The PosiTector 200 Advanced model can display up to three distinct layers, ensuring compliance with specifications and helping to identify problems within a system. - Support Compliance and Quality Control
Meets ASTM D6132 and ISO 2808 standards for ultrasonic thickness measurement, making it suitable for third-party inspection and audit documentation. - Applications Across Industries
- Construction & Flooring: Verify paint, sealants, and epoxy systems on concrete or timber.
- Marine & Fiberglass: Inspect barrier coats and gel coats on boats and yachts.
- Furniture & Woodworking: Ensure uniform finish thickness for quality assurance.
- Industrial Plastics & Composites: Validate coatings used in pipelines, aerospace, or automotive composites.

FAQ’s
What makes the PosiTector 200 different from other coating thickness gauges?
Unlike magnetic or eddy-current gauges, which only measure on metal substrates, the PosiTector 200 uses ultrasonic pulse-echo technology to measure coatings on non-metals such as wood, concrete, fiberglass, and plastics.
Can it measure individual coating layers?
Yes. The Advanced model can display thickness values for up to three separate layers, making it ideal for systems with primers, barrier coats, and topcoats.
What is “Max Thick” mode?
This mode is designed for porous or rough coatings. It filters multiple ultrasonic echoes and measures the maximum identifiable coating thickness.
Does it require couplant?
Yes. For smooth surfaces, water is sufficient. For rough or porous coatings, the included glycol-based gel provides better coupling.
What are the typical applications of the PosiTector 200?
-
Flooring: epoxies and sealants on concrete.
-
Marine: gel coats and fiberglass laminates.
-
Wood: paints, varnishes, and clear coats.
-
Industrial: coatings on plastic or composite pipelines and equipment.
How accurate is it?
It provides accuracy to ±(2 µm + 3% of reading). For high-precision applications, the included calibration shims can be used to verify accuracy on-site.
Does it comply with international standards?
Yes. It conforms to ASTM D6132, ISO 2808, ISO 19397, and other relevant standards for ultrasonic thickness measurement.
How often should it be recalibrated?
We recommend annual recalibration. DFT provides local, one-day turnaround calibration services with traceable certificates.
