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.
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
