DeFelsko PosiTector 200 C3 Advanced Ultrasonic Coating Thickness Gage for Concrete and Non-Metal Substrates
SKU: 200C3
An ultrasonic coating thickness gage that non-destructively measures coatings on concrete, fiberglass and other non-metal substrates from 50 to 3,800 µm, with the Advanced body's multi-layer measurement, graphics mode, 250,000-reading memory, WiFi and Bluetooth.

| 50–3800 µm2 to 150 mils range | 3 layersIndividual layer thickness | 250,000Stored readings | WiFi + BTWireless connectivity |
The DeFelsko PosiTector 200 C3 uses proven ultrasonic technology to non-destructively measure coating thickness over concrete, fiberglass and other non-metal substrates, where magnetic and eddy current gages can't work. The ultrasonic signal travels through the coating and reflects back from each interface, giving a fast, accurate thickness reading without damaging the coating.
It pairs the removable cabled 200 C probe with the PosiTector Advanced body. You can measure the total thickness of a coating system or up to 3 individual layers, analyze them in graphics mode, and store and share results over WiFi and Bluetooth. It conforms to ASTM D6132 and ISO 2808 and is backed by a two-year warranty on body and probe.

Key Features
![]() | Made for concrete and non-metalsThe 200 C probe measures coatings from 50 to 3,800 µm (2 to 150 mils) over concrete, fiberglass and other non-metal substrates. That makes it ideal for floor coatings, linings and waterproofing membranes, with no adjustment needed for most applications. |
Up to 3 layers with graphics modeAdvanced models measure the total thickness of a coating system plus up to 3 individual layer thicknesses, down to 50 µm (2 mils) per layer depending on the material. The graphic display shows each layer interface as a peak, and screen capture saves the view for your reports. | ![]() |
![]() | Advanced memory and wireless connectivityStore 250,000 readings in up to 1,000 batches, and rename batches or add notes with the touchscreen keyboard. WiFi synchronizes with PosiSoft.net and downloads updates, and Bluetooth 4.0 sends data to the PosiTector App or an optional portable printer. |
Built for the Field
Max Thick Mode
Max Thick Mode displays the deepest ultrasonic echo, so you don't need to adjust the Lo Range. It's ideal for ignoring unwanted surface echoes on rough or textured surfaces.
Simple, durable and accurate
It has a large 2.8" impact-resistant color touchscreen, on-gage help and an IP65 weatherproof, dustproof enclosure. A Long Form Certificate of Calibration traceable to NIST or PTB is included.
Integration and reporting
A BLE API and industry-standard protocols let the gage integrate with third-party software, drones, ROVs, PLCs and robotic devices. The PosiSoft suite of software handles viewing, reporting and archiving.
