DeFelsko PosiTest AT-M Manual Pull-off Adhesion Tester
The PosiTest AT Series measures the force to pull a specified test diameter of coatings or material away from its substrate using hydraulic pressure.
Measures adhesion of coatings to metal, wood, concrete and other rigid substrates.
- Portable - requires no external power sources - ideal for field or lab use
- 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
- 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
