Pull Off Adhesion Testers

DeFelsko PosiTest® Pull-Off Adhesion Tester

Pull Off Adhesion Testers measure adhesion of coatings to metal, wood, concrete and other substrates - Revolutionary self-alignment feature and pull rate indicator brings new meaning to adhesion measurements. Conforms to national and international standards including ASTM D4541/D7234, ISO 4624/16276-1, AS/NZS 1580.408.5 and other

Simple

  • Pull Rate Indicator allows operator to easily monitor and adjust the rate of pull in accordance with international test method
  • Easily select dolly sizes, change measurement units or store readings, with the touch of a button
  • Conversion charts not required - tester automatically calculates pressure based on dolly size
  • Inexpensive, single-use dollies eliminate cleaning for re-use and can be kept as a permanent record
  • Each kit comes with everything needed for testing

Self-Alignment Feature
Self Alignment

The PosiTest Adhesion Tester self-alignment feature compensates for misalignment.

  • Can be used in any position
  • Rugged carrying case
  • 24 Month warranty

Accurate

  • Every PosiTest Adhesion Tester pressure system is calibrated and certified to ± 1% accuracy using NIST traceable load cell
  • Self-aligning aluminum dolly enables accurate measurements on smooth or uneven surfaces
  • Hi-grade, industrial pressure sensor ensures continued accuracy
  • Conforms to national and international standards including ASTM D4541/D7234, ISO 4624/16276-1, AS/NZS 1580.408.5 and others

Versatile

  • Internal Memory stores maximum pull-off pressure, rate of pull, test duration and dolly size
  • Optional PosiSoft® software available for downloading
  • LCD displays pressure value in psi or MPa
  • 10, 14, 20 or 50 mm dollies maximize capability and measurement resolution across a wide range of bond strengths

Two Models (now available in Manual or Automatic)

The PosiTest Pull-Off Adhesion Tester measures the force required to pull a specified test diameter of coating away from its substrate using hydraulic pressure.

The PosiTest AT-A automatic features an electronically controlled hydraulic pump which automatically applies smooth and continuous pull-off pressure at a user-specified rate.

The PosiTest AT manual features a heavy-duty manual hydraulic pump designed to apply smooth and continuous pull-off pressure with a single stroke.
