Supports the following standards: BS 1881 PART 207, EN 1542, EN 1015, EN 1348, ISO 4624 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.
