Using ultrasonic pulse technology and requiring a couplant gel for measurement, the PosiTector 200 reads time-of-flight of sound through coatings to detect total and, in advanced models, individual layer thicknesses. Different probes—B, C, D—are optimized for thin to thick coatings. Features include onboard graphing, large storage (up to 250,000 readings), USB, WiFi & Bluetooth connectivity, live stats (avg/min/max/SD). Conforms to standards such as ASTM D6132, ISO 2808.
DeFelsko PosiTector 200 Coating Thickness Gauge for Non-Metal Substrates
This instrument delivers precise evaluation of coatings over non-metal materials using proven ultrasound technology. Ready to use out of the box, it offers robust construction, ergonomic design, and compliance with ASTM and ISO standards. Its advanced options support up to three coating layers, graphic display, and over 250,000 readings storage.
Features
Overview
| Model | Application | Measurement Range | Accuracy | Additional Notes |
|---|---|---|---|---|
| 200 B1 | Polymer coatings on wood, plastic, etc. | 13 to 1,000 μm / 0.5 to 40 mils | ±(2 μm + 3 % of reading) / ±(0.1 mils + 3 %) | Certified standard: STDA3 |
| 200 C1 | Coatings on concrete, fiberglass, etc. | 50 to 3,800 μm / 2 to 150 mils | ±(2 μm + 3 % of reading) / ±(0.1 mils + 3 %) | Certified standard: STDP6 |
| 200 D1 | Thick, soft coatings (polyurea, asphaltic neoprene) | 50 to 7,600 μm / 2 to 300 mils | ±(20 μm + 3 % of reading) / ±(1 mil + 3 %) | Certified standard: STDP1 |
| 200 B3 (Advanced) | Polymer coatings (multi-layer measurement) | Same total range; minimum layer ≈ 13 μm (0.5 mil) | Same base accuracy | Supports individual layer thickness; advanced model |
| 200 C3 (Advanced) | Coatings on concrete/fiberglass (multi-layer) | Same total; min layer ≈ 50 μm (2 mils) | Same base accuracy | Advanced model for multiple layers over concrete |
| 200 D3 (Advanced) | Thick, soft multi-layer coatings | Same total; min layer ≈ 500 μm (20 mils) | Same base accuracy | Best for very thick, soft coatings |
