Dy-2 Pull Off Tester

Dy-2 Pull Off TesterThe DY-2 family of automated pull-off testers covers the complete range of pull-off applications with unmatched ease of operation and a unique capability to store a complete record of the test.
The DY-2 is further unique in that it records every single test parameter required by the specification.

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

For the very first time, the operator is able to provide a complete record of the pull-off test, proving that the test was carried out in accordance with the applicable standard.
Three versions of DY-2 are available differentiated by maximum pulling force. This covers the complete range of pull-off applications (examples for Ø 50mm test discs) for normal, low strength such as mortar or high strength such as carbon fibre reinforced polymer.

DY – 2 Models

  Working Range*  
  Tensile Force Test Disk Ø 50 mm  
Dy-206  0.6 - 6 kN 0.3 - 3.1 MPa   
135 - 1349 lbf 44 - 443 psi   
Dy-216  1.6 15.5 kN 0.81 - 7.8 MPa  
360 - 3485 lbf 118-1145 psi   
Dy-225  2.5 kN - 25 kN 1.3 - 12.7 MPa  
562 - 5620 lbf 185 - 1847 psi  


DY-206 has increased accuracy for low strength applications such as testing adhesive strength of mortars and renders. DY-216 covering most applications. DY-225 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.

  • Integrated, feedback controlled motor removes operator variations by fully automated testing at a constant load rate which can be verified.
  • Full data logging including failure mode entry options for up to 
  • Automatic calculation of strength for different test discs without re-calibration of system
  • Dy-Link software displays complete record of test including load rate graph
  • Wide range of test disks / dollies

Applications

  • Concrete or shotcrete tensile strength measurement
  • Measuring the bond of overlays, renders or repairs
  • Coating adhesion 
  • Pull off testing is also used for exotic testing applications such as testing the integrity of laminated carbon brake disks

  • Failure mode reporting – The Dyna is unique in allowing the operator to record the location of the break during a test in the same record as the strength measurement.
  • Six month mechanical and 2 year electronic component warranty
  • Dy-2 is calibrated to EN ISO 7500-1 Class 1, this calibration exceeds the accuracy requirements of all standards stated later in this brochure
