Pinhole inspection unit

C12570 series

null

The C12570 series is designed to inspect pinhole defects in aluminum laminated film and metal foil. Among pinhole inspection units for film, the C12570 series has the highest sensitivity capable of pinhole detection down to 2 μm in diameter making it ideal for strict inspection applications where no pinholes are allowed and where precise inspections are a higher priority than high-speed conveyance.
