The PositTest Adhesion Tester (PosiTest AT) measures the force required to pull a specified test diameter of coating or material away from its substrate using hydraulic pressure. Maximize measuring capacity across low to high bond strengths for coatings to metal, concrete, wood, or plastic, or tile. Adapt to any situation with the Self Aligning Dolly on smooth or uneven surfaces. Automatic and Manual Models Available
**Custom 10 and 14 mm dollies are available for special applications (compatible with 20 mm stand off)- 10 mm: 10000 psi (70 MPa)
Both the PosiTest AT-M Manual and PosiTest AT-A Automatic models 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.
-Swipe horizontally to navigate between views or vertically to move between batch readings. Alternatively, the keypad can be used for navigation and selection.
-Record the results as pass/fail and the nature of fracture - cohesive, adhesive and glue failures
-Differentiate Between Cohesive and Adhesive Fractures as well as Glue Failures.
-The cohesive and adhesive fracture visual analysis can be recorded using the PosiTest AT-A's keypad or touch screen display. Alternatively, the information can be reported using the PosiTector App in accordance with ASTM D4541 and ISO 4624.
Typical applications for the PosiTest AT vary depending on their Stand off Size
Powerful desktop software for downloading, archiving, and reporting measurement data. No internet connection required.
An easy-to-use mobile app (iOS/ Android) that connects to your PosiTector Advanced, PosiTector Smartlink, or PosiTest AT-A.
A simple gage interface to retrieve data in a manner similar to a flash drive. No software to install or internet connection required.
