All Model Features
  • Environmentally sealed enclosure - weatherproof, dustproof and shockproof - meets or exceeds IP65
  • Inexpensive, single-use dollies eliminate cleaning for re-use and can be kept as a permanent record
  • 10, 14, 20 or 50 mm dollies maximize capability and measurement resolution across a wide range of bond strengths
  • Calibrated and certified to ± 1% accuracy using a NIST traceable load cell
  • Self-aligning aluminum dolly enables accurate measurements on smooth or uneven surfaces
PosiTest AT-A Automatic
  • Electronically controlled hydraulic pump automatically applies smooth and continuous pull-off pressure. Greatly reduces user effort and the risk of influencing the pulling process

Test Dollies

top
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

top

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.
