DeFelsko PosiTest AT-A Automatic Pull-off Adhesion Tester, 20mm Kit - ATA20A-B
The PosiTest AT Series measures the force to pull a specified test diameter of coatings or material away from its substrate using hydraulic pressure.
Measures adhesion of coatings to metal, wood, concrete and other rigid substrates.
- Portable - requires no external power sources - ideal for field or lab use
- Select from four Stand-offs - 20 mm, 50 mm, 50x50 mm Tile and 50 mm C1583
- Environmentally sealed enclosure – weatherproof, dustproof and shockproof - meets or exceeds IP65
- Inexpensive, single-use dollies eliminate cleaning for re-use and can be kept as a permanent record
- Self-aligning aluminum dolly enables accurate measurements on smooth or uneven surfaces
- 10, 14, 20 or 50 mm dollies maximize capability and measurement resolution across a wide range of bond strengths
- Calibrated and certified to ± 1% accuracy using a NIST traceable load cell
- Conforms to international standards including ASTM C1583/D4541/D7234/D7522, ISO 4642/16276-1, BS EN 12004-2, AS/NZS 1580.408.5 and others

PosiTest AT-A Automatic
- Electronically controlled hydraulic pump automatically applies smooth and continuous pull-off pressure. Greatly reduces user effort and the risk of influencing the pulling process
- 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 touch screen with keypad for operation with or without gloves
- Built-in rechargeable battery performs over 200 tests per charge. Continue testing with AC power while the battery recharges.
- Environmentally sealed enclosure – weatherproof, dustproof and shockproof - meets or exceeds IP65
- Rubberized, shock absorbing grips provide a stable, skid-resistant footing
- Self-aligning aluminum dolly enables accurate measurements on smooth or uneven surfaces
- 10, 14, 20 or 50 mm dollies maximize capability and measurement resolution across a wide range of bond strengths. Maximum pull-off pressure by dolly size...
- 10 mm: 14000 psi (96 MPa)
- 14 mm: 7000 psi (50 MPa)
- 20 mm: 3500 psi (24 MPa)
- 50 mm: 560 psi (3.8 MPa) - User selectable measurement units: psi (pounds per square inch), MPa (Megapascal), Nmm2 (Newtons per millimeter square) or Newton (force)
- User adjustable pull rate, pull limit and hold time
- Rotating display for horizontal and vertical use
- Pressure system is calibrated and certified to ± 1% accuracy using a NIST traceable load cell
- Compatible with PosiSoft Desktop, PosiSoft.net and PosiTector App (Apple iOS and Android)
