  • 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,
