Aircraft painting: precision landing in coating thickness measurement

According to projections, innovative, micrometre-precise paint finishes alone can save around 20 per cent of coating material in aviation. And the lighter a machine is, the less fuel it consumes, the better its CO2 balance.

No wonder that optimal coating has become a competitive factor in terms of savings and sustainability. OptiSense impressively demonstrates this by testing the coating application at its aviation customers. Learn more in the presentation during IntAirCoat on 6 June in Seville (Spain).

Thanks to all! OptiSense ranked first

We are excited! Because we take the 1st place in the overall ranking for the best cover picture 2022 in the trade magazine JOT. In the winning photo, our PaintChecker Mobile is checking the coating thickness on a rim - with its small measuring spot, it can check even the tightest corners and sharpest edges.

We would like to thank all JOT readers who voted for us for this great result!
