DeFelsko PosiTest AT Manual and Automatic Pull-off Adhesion Testers

The PosiTest AT Pull-off Adhesion Testers measure the adhesion of coatings on various rigid substrates like metal, wood, and concrete. They offer four stand-off options and feature an environmentally sealed enclosure that is weatherproof, dustproof, and shockproof, meeting or exceeding IP65 standards. The testers use inexpensive, single-use dollies that can be retained as permanent records, and a self-aligning aluminum dolly ensures accurate measurements on both smooth and uneven surfaces. Available in 10, 14, 20, or 50 mm sizes, the dollies enhance capability and resolution across different bond strengths. The testers are calibrated and certified to ± 1% accuracy with a NIST traceable load cell, and they include a Certificate of Calibration with NIST traceability.

PosiTest AT-A Key Features
