PosiTest AT-M Manual Pull-Off Adhesion Tester

Measures the force required to pull a specified test diameter of coating away from its substrate using hydraulic pressure.


Key Features...

  • Manual hydraulic pump designed to apply smooth and continuous pressure with a single stroke
  • Pull Rate Indicator to manually monitor and adjust the rate of pull
  • Environmentally sealed enclosure – weatherproof, dustproof and shockproof - meets or exceeds IP65
  • 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
    • 10 mm: 10000 psi (70 MPa)
      14 mm: 6000 psi (40 MPa)
      20 mm: 3000 psi (20 MPa)
      50 mm: 500 psi (3.5 MPa)
  • Every PosiTest Adhesion Tester pressure system is calibrated and certified to ± 1% accuracy using a NIST traceable load cell
  • Internal memory stores maximum pull-off pressure, pull rate, test duration and dolly size for up to 200 pulls
  • Compatible with PosiSoft Desktop software for viewing, printing and storing measurement data
  • Conforms to international standards including ASTM D4541/D7234, ISO 4624/16276-1, AS/NZS 1580.408.5 and others
