Pull-off Adhesion Testers
Measures adhesion of coatings to metal, wood, concrete and other rigid substrates.
- Select from four Stand-offs – 20 mm, 50 mm, 50×50 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
- Certificate of Calibration showing traceability to NIST included (Long Form)
EN 1542/12004-2, AS/NZS 1580.408.5 and others
