Description
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.
PosiTest AT-A Automatic
- Electronically controlled hydraulic pump automatically applies smooth and continuous pull-off pressure, reducing risk of influencing the pulling process
- Switchable measurement units: psi, MPa, Nmm2, Newman
- Pull rate, pull limit, and hold time are all user-adjustable
- Internal memory stores maximum pull-off pressure, rate of pull, test duration, dolly size, pass/fail, nature of fracture, and user notes for 100,000 pulls in up to 1,000 batches
- Impact and scratch resistant color touchscreen with keypad
- Rubberized, shock absorbing grips for a stable, skid-resistant footing
- PosiSoft Desktop, PosiSoft.net, and PosiTector App compatible (Apple iOS and Android)
PosiTest AT-M Manual
- Manual hydraulic pump designed to apply smooth and continuous pressure with a single stroke
- Switchable measurement units: psi, MPa
- Pull rate indicator for manually monitoring and adjusting the rate of pull.
- Internal memory in the manual model stores maximum pull-off pressure, rate of pull, test duration, dolly size for up to 200 pulls
- PosiSoft Desktop compatible for viewing, storing, and printing measurement data
