PosiTest AT-A Automatic Adhesion Tester by DeFelsko

The New DeFelsko POSITEST AT-A AUTOMATIC ADHESION TESTER is DeFelsko's newest pull-off adhesion tester. PosiTest Automatic Adhesion Tester features an electronically-controlled hydraulic pump: no more manual priming, or pumping of the hydraulic system. Now coatings adhesion testing is performed with the push of a button!

The PosiTest Automatic Adhesion Tester also features user-selectable pull rate for conformance to international test standards for a wide range of applications. A full digital keypad allows the user to select pull-off pressure, pull rate, dolly size, as well as to change measurement units or store readings in the gauge. PosiTest Automatic Adhesion tester also features a built-in, rechargeable battery, shoulder strap, and AC power for greater versatility and convenience of use. The PosiTest AT Automatic Adhesion Tester has the PosiTest self-aligning dolly system: a ring of ball bearings in the grip mechanism of the actuator allow the dolly-head to articulate to compensate for uneven surfaces, making a proper, vertical pull possible and ensuring reliable, repeatable test results.
 

PosiTest Automatic Adhesion Tester shares many of the best features of the PosiTest Manual Adhesion Tester.
