Gardco :: Positest Pull-Off Adhesion Test

Features

All Model Features Environmentally sealed enclosure - weatherproof, dustproof and shockproof - meets or exceeds IP65 Inexpensive, single-use dollies eliminate cleaning for re-use and can be kept as a permanent record 10, 14, 20 or 50 mm aluminum dollies maximize capability and measurement resolution across a wide range of bond strengths Calibrated and certified to ± 1% accuracy using a NIST traceable load cell Self-aligning aluminum dolly enables accurate measurements on smooth or uneven surfaces
PosiTest AT-A Automatic Adhesion Test 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 Built-in rechargeable battery performs over 200 tests per charge. Continue testing with AC power while the battery recharges Internal memory stores maximum pull-off pressure, rate of pull, test duration, dolly size, pass/fail, the nature of fracture and user notes for 100,000 pulls in up to 1,000 batches New graphical display Compatible with PosiSoft desktop software, PosiSoft.net and PosiTector App PosiSoft USB Drive - stored readings and graphs can be accessed using universal PC/Mac web browsers or file explorers No software required WiFi technology wirelessly communicates with PosiSoft.net and downloads software updates Rubberized, shock absorbing grips also provide a stable, skid-resistant footing Impact and scratch resistant color touch screen with keypad for operation with or without gloves
PosiTest AT-Manual Adhesion Test Manual hydraulic pump designed to apply smooth and continuous pressure with a single stroke Pull Rate Indicator to manually monitor and adjust the rate of pull Internal memory stores maximum pull-off pressure, rate of pull, test duration and dolly size for up to 200 pulls Compatible with PosiSoft desktop software New graphical display Compatible with PosiSoft desktop software, PosiSoft.net and PosiTector App PosiSoft USB Drive - stored readings and graphs can be accessed using universal PC/Mac web browsers or file explorers No software required WiFi technology wirelessly communicates with PosiSoft.net and downloads software updates Rubberized, shock absorbing grips also provide a stable, skid-resistant footing Impact and scratch resistant color touch screen with keypad for operation with or without gloves

Test Dollies

The PosiTest® Adhesion Test uses inexpensive
single-use aluminum dollies designed according
to internationally accepted standards and practices. Available with full 10, 14, 20 or 50 mm surface dimensions for different shapes and bond strengths.

The uniquely spherical articulating dolly head is engaged into a ring of small ball bearings, ensuring correct alignment. This feature is found only on the PosiTest® Adhesion Tester.

Self-Alignment Feature

Alignment Feature

Unequal pulling force during testing caused by uneven adhesive bond lines and coating surfaces can result in random, unexplainable readings.

To obtain more repeatable and meaningful adhesion measurements, it is imperative that the pulling force applied to the test dolly is uniformly distributed over the surface being tested.

The Self-Aligning Dolly enables uniform distribution of the pulling force over the surface being tested, preventing a one-sided pull-off.
