AT-A Automatic
New electronically controlled hydraulic pump automatically applies smooth and continuous pull-off pressure at a user-specified rate
â– Test with the simple push of a button. No twisting, pumping or cranking. No valves to close, needles to reset, or scales to adjust
â– User selectable pull rates ensure compliance with international test methods for a variety of industries including metal, wood and concrete
â– Built-in rechargeable batteries perform over 200 tests per charge. Continue testing with AC power while batteries recharge. Supplied with universal AC Adapter
â– Rugged, portable instrument comes complete with convenient shoulder strap. Ideal for lab and field use.Self-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.
Both the PosiTest AT manual and AT-A automatic compensate for misalignment. The self-aligning, quick-coupling actuator and spherical articulating dolly head enable uniform distribution of the pulling force over the surface being tested, preventing a one-sided pull-off.

AT Manual
â– Heavy-duty manual hydraulic pump designed to apply smooth and continuous pull-off pressure with a single stroke
â– Pull Rate Indicator to manually monitor and adjust the rate of pull
â– Includes built-in NiMH batteries with chargerSelf-Alignment Feature
