PosiTest AT manual adhesion tester / adhesion tester

Pull-Off adhesion tester

Measures the force required to detach a specified test area of a coating from the substrate using manually generated hydraulic pressure. This process is also called pull-off testing.

The adhesive tensile strength (Haftzugfestigkeit) (pull-off strength) serves as a characteristic value for the adhesion or bonding of layers such as plasters, screeds, coatings or paints on concrete surfaces. Adhesive tensile strength is determined using the adhesive tensile test (also known as the pull-off test).

Tensile adhesion test according to ISO 4624 and ZTV-ING (class 1 according to DIN 51220) with various devices from DeFresko

You have the choice between AT-M (Manual) and AT-A (Automatic)
