2 Models:
ATM20 - with stand-off, cutting tool and 20mm dollies for coatings on metals
ATM50 - with stand-off, cutting tool and 50mm dollies for coatings on wood, concrete and plastics

The DeFelsko PosiTest AT-M Measures adhesion of coatings to metal, wood, concrete and other substrates - Revolutionary self-alignment feature and pull rate indicator brings new meaning to adhesion measurements. A manual hydraulic pump is designed to apply smooth and continuous pressure with a single stroke.

The PosiTest AT-M features an environmentally sealed enclosure. It is weatherproof, dustproof and shockproof. Meeting or exceeding IP65rating.

Features 

• Conforms to international standards including ASTM D4541 / D7234, ISO 4624/16276-1, AS/NZS 1580.408.5 and others
• 10, 14, 20 or 50 mm dollies maximize capability and measurement resolution across a wide range of bond strengths
• User selectable measurement units: psi (pounds per square inch), MPa (Megapascal)
• Every PosiTest Adhesion Tester pressure system is calibrated and certified to ± 1% accuracy using a NIST traceable load cell
• Internal memory stores maximum pull-off pressure, pull rate, test duration and dolly size for up to 200 pulls
• Compatible with PosiSoft desktop software for viewing, printing and storing measurement data

ATM 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-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.
