Overview
The Defelsko Adhesion Tester PosiTest AT-A 20mm is a fully automated adhesion testing device with a 20mm kit and a maximum adhesion Measurement range of 3500 psi. The instrument automatically generates a smooth and continuous pull-out force through an electronically controlled hydraulic pump, effectively reducing the impact of uneven manual operation on measurement results. Equipped with touch keyboard operation and waterproof and dustproof housing, it is suitable for metal coating adhesion testing.
Features
1. Adopt color LCD screen and touch button operation, no need to wear gloves
2. The electronically controlled hydraulic pump automatically generates a smooth and continuous pulling force, reducing operating errors
3. Built-in rechargeable battery, each charge can be continuously tested 200 times, support AC power supply

5, with adsorption force rubber handle, the substrate is stable and non-slip
6, automatic alignment positioning kit, adapt to smooth or rough surface
7. Available in 10, 14, 20 and 50mm kits to meet different testing needs
8. User-adjustable tensile rate, tensile limit, and holding time
9. Supports horizontal and vertical testing, LCD screen can be swirled/spun
10. Pressure system verified by NIST Traceability, accuracy of +/- 1% (full scale)
Principle
The PosiTest AT-A 20mm pull-out adhesion instrument automatically generates a smooth and continuous pull-out force through an electronically controlled hydraulic pump. After adhering the kit to the coating surface, the instrument automatically applies the pull force until the coating peeling, measuring and recording the maximum adhesion value. Fully automatic operation reduces the influence of human factors on the test results.
Applications
Metal coating adhesion test
Standards
ASTM D4541、ASTM D7234、ISO 4624、ISO 16276-1、AS/NZS 1580.408.5
Steps
1. Use the trimmer to prepare the test surface
2. Adhere the kit to the coating surface
3. Set test parameters through Touchscreen
4. Start the automatic drawing test
5. Read and record test results
6. Data can be exported through the Positector APP
Notice
• Make sure the kit and coating surfaces are completely gluing before testing
• Choose the appropriate kit size according to the test material
• Measurement accuracy by calibrating instruments regularly
• Avoid use in extreme temperatures or Humidity environments
• AC power can also be used for testing during charging
• Pay attention to group management when storing data
