Pull-off Tester, DY-2

The quality of concrete repairs is determined by the adhesive strength between the repair material and the substrate. Pull-off testing is the most widely used test method to assess bond strength. The DY-2 family of automated pull-off testers covers the complete range of pull-off applications with unmatched ease of operation and the ability to store a complete record of the test. The DY-2 with its integrated feedback controlled motor provides a regulated load rate as specified by all standards, thereby providing a fully automated test for the most repeatable results. It is lightweight for easy operation even on walls and overhead.

The DY-2 pull-off testers are also unique, in that they record every single test parameter required by specifications:

• Test disc size
• Maximum load applied
• Automatic calculation of bond strength
• Applied load rate with graphical record
• Time and date of the test
• Complete time of test
• Failure mode

With the DY-2 pull-off testers, the operator is able to provide a complete record of the pull-off or bond test, proving that the test was carried out in accordance with applicable standards.

Three versions are available, the HC-2985: 135 – 1349 lbf (0.6 – 6kN) covers most common applications, while HC-2986: 360 – 3597 lbf (1.6 – 16kN) provides increased accuracy for low-strength applications, and, the HC-2987: 360 – 562 – 5620 lbf (2.5 – 25kN) can be used for very high strength applications such as testing of fibre-reinforced polymers bonded to concrete structures or testing the bond strength of repair and overlay materials.
