The Positest AT-A Automatic Adhesion Tester measures the force required to pull a specified test area of coating away from a substrate using hydraulic pressure. An electronically controlled hydraulic pump automatically applies smooth and continuous pull-off pressure. The pump greatly reduces user effort and the risk of influencing the pulling process.
The AT-A's built-in rechargeable battery performs over 200 tests per charge. The supplied AC adapter / charger allows you to continue testing with AC power while the battery recharges.
The AT-A is features an environmentally sealed enclosure. It is weatherproof, dustproof and shockproof. Meeting or exceeding IP65 rating.
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
Electronically controlled hydraulic pump automatically applies smooth and continuous pull-off pressure. Greatly reduces user effort and the risk of influencing the pulling process
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

Built-in rechargeable battery performs over 200 tests per charge. Continue testing with AC power while the battery recharges.
Rubberized, shock absorbing grips provide a stable, skid-resistant footing
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)
