PosiTest® AT-A Pull-off Adhesion Testers

Measures adhesion of coatings to metal, wood, concrete and other rigid substrates.

  • Electronically controlled hydraulic pump automatically applies smooth and continuous pull-off pressure. Greatly reduces user effort and the risk of influencing the pulling process
  • User adjustable pull rate, pull limit and hold time
  • 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
  • Compatible with PosiSoft DesktopPosiSoft.net and PosiTector App (Apple iOS and Android)
Conforms to international standards including ASTM C1583/D4541/D7234, ISO 4624/16276-1, EN 1542/12004-2, AS/NZS 1580.408.5 and others
