Proceq DY-2 automatic pull-off testers cover a wide range of pull-off tests with unmatched ease of use and test record storage capability. Tensile or adhesion (bond) testing is one of the most common testing methods in the construction industry. It has long been known that one of the major influences on the outcome of the tensile test is the user influence on applying a constant load speed. The Proceq DY-2 completely eliminates this variable by performing a fully automatic pull test at a constant load speed, which can be verified with its integrated feedback control motor.
