FLS High-Range

Measures intumescent paint and other thick protective coatings on steel. Measures up to 38 mm (1.5 inches). Braided stainless steel cable - kink-proof, wear and cut resistant. Includes hard shell case and 19 mm (750 mil) shim. Compatible with PosiTector bodies with serial numbers greater than 700,000 and the new PosiTector SmartLink.

Range: 0-38 mm, 0-1.5 in

FNGS Ultra High-Range

Measures very thick coatings non-conductive coatings on both ferrous and non-ferrous metal substrates. Ideal for measuring ship hull coatings and thick intumescent paints. Measures up to 63.5 mm (2.5 inches). Braided stainless steel cable - kink-proof, wear and cut resistant. Long-lasting, low wear probe face to facilitate scanning of large surfaces. Includes a handle for easy one-handed operation. Compatible with PosiTector bodies with serial numbers greater than 700,000 and the new PosiTector SmartLink.

Range:  0-63.5 mm, 0-2.5 in

FNDS Duplex Coatings Probe

The PosiTector 6000 FNDS probe measures the individual thicknesses of both the paint and the zinc layers in a duplex coating system with a single reading. In Duplex mode, the PosiTector 6000 FNDS utilizes both magnetic (ferrous) and eddy current (non-ferrous) principles simultaneously to calculate and display the individual paint and zinc layer thicknesses. The magnetic principle is used to measure the combined paint/zinc thickness over the ferrous substrate, and the eddy current principle is used to measure the paint thickness over the non-ferrous zinc coating. The zinc thickness is calculated by subtracting the paint thickness from the combined paint/zinc thickness measurement. Compatible with PosiTector Advanced (serial numbers 730,000+) and PosiTector Standard gage bodies with a color display. A gage update may be required.

Range: 0-60 mils (0-1500 µm)
