PosiTest® Pull-Off Adhesion Test

Article No. 5142

PosiTest ATA-20
Automatic Pull-Off Adhesion Tester

Electronically controlled hydraulic pump automatically applies smooth and continuous pull-off pressure
Greatly reduces user effort and the risk of influencing the pulling process
User adjustable pull rate, pull limit and hold time
A rechargeable NiMH battery is built-in providing up to 200 tests per charge
High resolution screen
Wireless connection to a smart device
Records the nature of the failure: cohesion, adhesion, or glue failure

Features

There are two models available. The model AT-A Automatic Pull-Off Adhesion Tester and Model AT manual version. Both models have the following features:

Portable, hand-operated instrument can be used in any position and requires no external power source-ideal for the lab and on-site
Large scale reads clearly and easily in PSI and MPa
Inexpensive, single-use dollies eliminate the need for heating, cleaning, or brushing for re-use
Self-aligning dolly enables measurement on smooth or uneven surfaces without adversely affecting the test results.
Heavy-duty hydraulic pump with safety valve helps prevent damage to pressure system
Quick-coupling makes securing dollies in actuator simple, fast and trouble-free
Multi-purpose, high-tensile two-part adhesive suitable for use with a wide variety of coatings and coating thicknesses
Cutting tool for isolating test area is included
Coating adhesion tester pressure system is calibrated and certified to ±1 % accuracy (full-scale) and comes with a two-year warranty
Internal memory stores up to 200 pulls. This includes maximum pull-off pressure, rate of pull, test duration, and dolly size
Optional PosiSoft software available to upload test results
USB Port PC interface
10, 14, 20, and 50mm dollies to maximize the measurement resolution and test range
