PosiTest Pull-Off Adhesion Tester NEW AT-A Automatic
  • New electronically controlled hydraulic pump automatically applies smooth and continuous pull-off pressure at a user-specified rate
  • Test with the simple push of a button. No twisting, pumping or cranking. No valves to close, needles to reset or scales to adjust
  • User selectable pull rates ensure compliance with international test methods for a variety of industries including metal, wood and concrete
  • Built-in rechargeable NiMH batteries rated IP65 and affording a high level of pretection against dust and water ingress, perform over 200 tests per charge. Continue testing with AC power while batteries recharge.
AT Manual
  • Heavy-duty manual hydraulic pump designed to apply smooth and continuous pull-off pressure with a single stroke
  • Pull Rate indicator to manually monitor and adjust the rate of pull

Test Dollies
Test Dollies

The PosiTest® Adhesion Tester uses inexpensive
single-use aluminum dollies designed according
to internationally accepted standards and practices. Available with full 10, 14, 20 or 50 mm surface dimensions for different shapes and bond strengths.

The uniquely spherical articulating dolly head is engaged into a ring of small ball bearings, ensuring correct alignment. This feature is found only on the PosiTest® Adhesion Tester.

Self-Alignment Feature

Alignment Feature

Unequal pulling force during testing caused by uneven adhesive bond lines and coating surfaces can result in random, unexplainable readings.

To obtain more repeatable and meaningful adhesion measurements, it is imperative that the pulling force applied to the test dolly is uniformly distributed over the surface being tested.

The Self-Aligning Dolly enables uniform distribution of the pulling force over the surface being tested, preventing a one-sided pull-off.
