The American made PosiTest AT-A Automatic Adhesion Tester measures adhesion of coatings to concrete, metal and other rigid substrates and now features an electronically controlled hydraulic pump to apply smooth and continuous pull-off pressure at user-selectable rates.
The PosiTest AT-A makes adhesion testing easy with the simple push of a button. No twisting, pumping or cranking required. Features include user selectable pull rates for complying with a variety of international test methods, built-in rechargeable batteries, convenient shoulder strap and AC power adapter.
Additionally, the PosiTest AT Manual Adhesion Tester is available with manual hydraulic pump and pull rate indicator.
Each PosiTest AT compensates for misalignment with a self-aligning actuator enabling evenly distributed pull-off force on both smooth and uneven coating surfaces. Conforms to national and international standards including ASTM D4541 and ISO 4624.
