Mechanical tests

Impact, scratch, abrasion are the mechanical constraints wich are very frequently applied for surface coatings. A lot of laboratory tests use the mechanical means for evaluating the physical properties of surfaces and coatings.

The NEW PosiTest AT-A Automatic Adhesion Tester measures adhesion of coatings to metal, wood, concrete and other substrates and now features an electronically controlled hydraulic pump. The new electric pump applies smooth and continuous pulloff pressure at user-selectable rates.

The PosiTest AT-A makes adhesion testing even easier. Now, you can test adhesion strength with just the touch of a button. No twisting, pumping or cranking required.

New features include electronically controlled hydraulic pump, user selectable pull rates for complying with a variety of international test methods, built-in rechargeable batteries,
convenient shoulder strap and AC power. Full digital keypad allows the operator to easily select dolly sizes, specify pull rate, change measurement units or store readings with just the touch of a button.

Additionally, the PosiTest AT Manual Adhesion Tester is available. The manual hydraulic pump was designed to apply smooth and continuous pressure with a single stroke. The
pull rate indicator allows the operator to manually monitor and adjust the rate of pull.
