Equotip 550 Leeb U

Versatile Leeb Hardness Tester for Rolls, Foils, and Films

The Equotip 550 Leeb U is a versatile Leeb hardness tester designed for on-site testing of large rolls, thin foils, and films. With a large spherical crown for safe, stable impacts on curved surfaces, it enables immediate visual assessment of hardness profile and direct data reporting. It’s built to test the hardness profile of paper, film, and foil rolls quickly and reliably, using the same rugged Equotip 550 touchscreen platform.
