PosiTest AT-A Automatic

The PosiTest AT-A is an automatic adhesion tester that performs precise pull-off tests, records the nature of fractures, and allows the generation of professional reports using the PosiSoft application.

The PosiTest AT-A is an automatic adhesion tester designed to perform coating pull-off tests with maximum precision and minimal user effort. Its electronically controlled hydraulic pump applies pressure smoothly and continuously, ensuring reliable and repeatable results in both laboratory and field environments.

Main features of the PosiTest AT-A

• Accuracy and control:
  • Smooth and continuous pull-off pressure via automatic hydraulic pump.
  • Adjustable pull-off rate, pull limit, and dwell time.
  • Calibration certificate traceable to NIST with ±1% accuracy.
  • Records PASS/FAIL results and fracture type (cohesive, adhesive, or glue).
• Ergonomics and durability:
  • Impact- and scratch-resistant color touchscreen, operable with gloves.
  • Sealed enclosure resistant to weather, dust, and impacts (IP65).
  • Rubberized grips and self-aligning aluminum dollies for accurate measurements on smooth or irregular surfaces.
  • Rechargeable lithium-ion battery with more than 250 tests per charge.
• Versatility and connectivity:
  • Compatible with the PosiSoft App (iOS and Android) to add notes, photos, and generate PDF reports.
  • Bluetooth connection for data synchronization and WiFi for updates and remote access.
  • USB-C port for fast charging and data transfer.
  • Selectable measurement units: psi, MPa, N/mm², or Newton.

Scope and capabilities

Benefits of the PosiTest AT-A adhesion tester

• Reduces user effort and minimizes errors caused by manual influence.
• Allows detailed analysis of up to five coating layers.
• Compatible with PosiSoft Desktop and PosiSoft.net software for data storage and report generation.
• Ensures compliance with international standards: ASTM C1583, ASTM D4541, ISO 4624, EN 1542, EN 12004-2, and others.

How does it work?

1. Select the appropriate dolly and apply the adhesive.
2. Place the PosiTest AT-A tester and run the automatic test.
3. Observe the PASS/FAIL reading and record the fracture: cohesive, adhesive, or glue.
4. Connect the unit to the software to store data and generate professional reports.

Frequently Asked Questions (FAQ)

On which surfaces can the PosiTest AT-A be used?
It works on metal, wood, concrete, plastic, and cementitious adhesives, including multi-layer coatings.

Can it be used in both field and laboratory?
Yes, it is portable, lightweight (5.5 kg), and resistant to impacts, dust, and moisture—ideal for both environments.

Can test data be stored and reports generated?
Yes, it records up to 100,000 pull-offs in 1,000 batches and allows data export via USB or the PosiSoft App.

What is the difference between the PosiTest AT-A and AT-M?

• PosiTest AT-A: Automatic, electric motor, rechargeable battery, touchscreen, records up to 100,000 tests, connects to PosiSoft App and WiFi.

• PosiTest AT-M: Manual, requires hand-operated hydraulic pumping, memory for 200 tests, basic LCD screen, more portable and simple, ideal for users who prefer a mechanical device.

Which tester is more suitable for laboratory or field?

• AT-A: Ideal for repetitive tests and large batches, advanced fracture analysis, and digital report generation.

• AT-M: Perfect for quick tasks or environments where simplicity and low maintenance are required.
