2 – 60 mm Measurable thickness S355, mill scale, lift-off up to 2 mm, 20 °C
0.08 mm Measurement accuracy S355 reference block, lift-off 1 mm, 20 °C
3 mm Validated lift-off Coated carbon steel, coating up to 3 mm
18 min Flight time At full battery charge, no wind

How a measurement flight works

Demo narrative. The rotary mast holds the EMAT sensor against inclined, horizontal and overhead surfaces, so one flight covers geometry that would otherwise need scaffolding. Every figure on this staging site is invented.
