The Elcometer 506 Pull-Off Adhesion Tester is a lightweight, portable and easy-to-use instrument suitable for measuring the tensile strength of coatings up to 50 MPa (7250 psi), either on-site or in the laboratory.

Accurate and repeatable

The design of the Elcometer 506 adhesion tester ensures that, by smoothly turning the operating handle, the user can easily apply a consistent force across the entire measurement range, delivering repeatable adhesion results with an accuracy of ±1%.

Quick coupling and accessories

The Elcometer 506 quick coupling allows easy attachment of 14.2 mm, 20 mm or 50 mm diameter dollies, which, together with a range of accessories, enables coating adhesion testing on flat, convex, thick and thin substrates — including metal, wood, concrete and other fibrous materials.

Ergonomics and safety

The Elcometer 506 test head is designed to be small, ergonomic and lightweight — ideal for one-handed coating adhesion testing even in awkward or confined spaces. Safe adhesion testing on vertical surfaces has also been taken into account: using the magnetic clamp accessory, the actuator is held securely, thereby preventing accidental damage to surrounding areas.
