On-line testing directly in the production line saves time and money. Downloads Leaflet (PDF) Special features Wide measuring ranges: air permeability: 1 – 5’000 mm/s (0.2 – 1’000 ft³/ft²/min), thickness: 0 – 6 mm. High measuring accuracy. Measures cross profiles, length profiles and zigzag profiles. Handles web speeds of up to 200 m/min (660 ft/min). (!) High resolution of up to 1 mm test point pitch. The modular system adapts easily to the requirements of the production line. Calibratable.
