DYNA Estrich Pull-off Tester

DYNA Estrich

The DYNA pull-off tester determines the adhesive strength on different surfaces in a user-friendly way. Main applications are the testing of adhesive strength of coatings on concrete structures and the tensile strength of concrete.

Testing can be carried out on any point of a structure without having to install test devices prior to the casting of concrete.

The DYNA tester is indispensable for the diagnosis of building structure damages as well as for checking completed renovation work.


  • Integrated digital manometer (with metric and imperial units)
  • Mobile and suitable for use in any location
  • Lightweight and precise
  • Independent of mains supply due to easily running crank drive
  • Constant jolt-free load increase
  • An optional electrical drive unit is available


  • Measurement of the adhesive strength of applied coatings e.g. plastic or concrete coatings, mortars, plasters, bituminous coats and coatings on metal
  • Determination of the surface strength of concrete and other materials
  • Ideal for the evaluation of tensile strength in concrete renovation

Product Variations
