The Automatic Pull-Off Adhesion Tester is designed to measure the adhesion strength of coatings on metal, concrete, and other substrates. The instrument uses a hydraulic system to pull off a defined area of the coating from the substrate surface. The multi-function touch LCD screen displays the entire adhesion testing process in real time, providing clear, intuitive feedback
