DeFelsko PosiTest ATA20 Automatic Adhesion Tester

DeFelsko PosiTest ATA20 Automatic Adhesion Tester

In industries demanding stringent acceptance standards such as shipbuilding, oil and gas, large-scale steel structures, and construction, the adhesion of a coating layer to the substrate material is the most critical technical parameter determining structural lifespan. The DeFelsko PosiTest ATA20 adhesion tester is currently the most advanced automatic hydraulic pull-off equipment from DeFelsko (USA). The device completely eliminates errors caused by human operation, delivering absolute measurement precision and holding high technical-legal data value globally.

The DeFelsko PosiTest ATA20 belongs to the category of fully automatic pull-off adhesion testers for coatings. The device utilizes an integrated hydraulic pump powered by a smart electric motor to pull off a standard 20mm dolly that has been securely bonded to the coating surface using a specialized adhesive.

The core distinction of the ATA series compared to traditional manual models is its capability to precisely control the pull rate according to pre-configured settings. The gage perfectly complies with the most rigorous international certifications such as ASTM D4541, ISO 4624, ISO 16276-1, and AS/NZS 1580.408.5.

Key Features of the DeFelsko PosiTector ATA20

💡 Automatic Motorized Hydraulic Pump – Eliminating Human Errors

With just a single button press, the electronic pump system automatically increases hydraulic pressure smoothly and continuously. This feature completely eliminates sudden pressure spikes or jerking caused by a technician’s manual stroking, ensuring the most objective and accurate measurement results in strict accordance with ASTM/ISO standards.

💡 Intelligent Touchscreen and Expansive Storage Memory

• The instrument is equipped with a sharp, scratch-resistant industrial touchscreen that intuitively displays real-time pull-off force charts.
• Massive storage capacity: Records comprehensive data for thousands of measurements, including maximum pull-off force, actual pull rate, test duration, and dolly size.
• Users can effortlessly log the nature of the fracture (cohesive, adhesive, or glue failure) directly on the screen after completing the pull-off process.

💡 20mm Dollies Optimized for Metal Structures

The ATA20 version comes supplied with a specially engineered system of 20mm diameter aluminum dollies. This size yields the ideal force measurement range for auditing anti-corrosive primers, powder coatings, and protective layers on steel structures, industrial tanks, and oil and gas pipelines.

💡 Durable Housing with IP65 Weatherproofing Standard

Despite being an intelligent electronic device, the DeFelsko PosiTest ATA20 possesses incredible ruggedness. The housing features water and dust resistance conforming to the IP65 standard. The entire instrument and its auxiliary accessories (cutting tools, adhesives, dollies) are securely protected inside a heavy-duty, impact-resistant plastic carrying case, ready to withstand harsh environments on offshore rigs or dusty shipyards.

💡 Unlimited Connectivity and Automated Reporting

The gage supports a USB port for computer connection along with wireless Bluetooth/Wi-Fi technologies. Users can easily synchronize data with the free PosiSoft software on a PC or mobile apps for cloud data management, plotting in-depth analysis charts, and automatically generating formatted PDF inspection reports to send to project investors.
