The Defelsko PosiTest AT-A 50mm Pull-Off Adhesion Tester is a fully automated pull-off adhesion Tester for testing the adhesion of coatings on lower adhesion coatings. automaticPull-off adhesion TesterIt can automatically align and position the top, not only on smooth surfaces, but also on rough surfaces can be accurately measured, the maximum adhesion force range for measurement is 560psi, and can be connected to the APP to operate measurement and manage data.
1、Pull-off adhesion TesterThe built-in memory can store up to 100,000 pieces of data(including tensile force value, pressurization rate, test time, and top size), which can be divided into 1000 groups.
2. Record the adhesion test results (pass/fail) and the firmness of adhesion (good, fair, poor).
3. You can install the free Positector APP on your mobile device and connect wirelessly. (Available for IOS and Android)


1. Color LCD screen, touch button operation, no need to wear gloves.
2、PosiTest AT-A 50mmPull-off adhesion TesterIt adopts an environmentally friendly sealed shell, which fully meets and exceeds the IP65 level, and has strong waterproof, dustproof and shockproof characteristics.
3. The electronically controlled hydraulic pump automatically produces a smooth and continuous pulling force. Reduce the influence of uneven force on the measurement results caused by manual operation of the staff.
4. Built-in rechargeable battery, each charge can be continuously tested 200 times. While the battery is charging, AC power can also be used for testing.
5、PosiTest AT-A 50mmPull-off adhesion TesterRubber grip with adsorption for a stable and non-slip base.
6. The user can adjust the tensile rate, the limit of the tensile force and the holding time.
7. Automatically align and position the top sub, so that it can be accurately measured on smooth or rough surfaces.
8. There are 10, 14, 20 and 50mm jacks to meet the test needs of different adhesion ranges.
10mm: 1400psi (96MPa); 14mm:7000psi(50MPa);
20mm:3500psi(24MPa);50mm:560psi(3.8MPa)
9. The PosiTest AT-A 20mm pull-off adhesion Tester can be tested horizontally or vertically, and the LCD screen can be rotated for display.
10. The pressure system is calibrated by traceable NIST load cell, and the accuracy reaches ±1% (full scale)



1. Add pictures or text through the camera or keyboard.
2. Create customized, professional PDF reports.
3. Measurement data can be shared, backed up, synchronized and recorded.
4. Automatic pairing Bluetooth (BLE) connection.
5. Check the help manual to learn how to use it.
