DeFelsko PosiTest ATA50A Automatic Pull-Off Adhesion Tester With 20mm Dollies Kit ATA20A-B Range:  0,7 - 24 MPa / 100 - 3500 psi / 100 - 7550 N. The DeFelsko PosiTest AT Pull-off Adhesion Tester is ideal for measuring coating adhesion to metal, wood, concrete, and other rigid substrates. The PosiTest AT has an environmentally-sealed, industrial-strength aluminum  housing enclosure that meets or exceeds IP65, making it dustproof, waterproof, and shockproof. A high-contrast color display allows readings to be displayed with clarity. The user interface and keypad have been updated to provide a better user experience during long inspections.

The PosiTest AT conforms to international standards including ASTM C1583/D4541/D7234/D7522, ISO 4624/16276-1, EN 1542/12004-2, AS/NZS 1580.408.5, and others. All PosiTest Adhesion Testers include field-replaceable AAA alkaline batteries as well as a rechargeable NiMH battery for up to 16 hours of testing.

Single-use dollies are self-aligning and can be kept as permanent records and eliminate cleaning for reuse. The aluminum dollies enable accurate measurements on both smooth and uneven surfaces, coming in sizes of 10, 14, 20, and 50 mm for measurement across a broad range of bond strengths.
