Description

The PosiTest AT Pull-off Adhesion Testers measure the adhesion of coatings on various rigid substrates like metal, wood, and concrete. They offer four stand-off options and feature an environmentally sealed enclosure that is weatherproof, dustproof, and shockproof, meeting or exceeding IP65 standards. The testers use inexpensive, single-use dollies that can be retained as permanent records, and a self-aligning aluminum dolly ensures accurate measurements on both smooth and uneven surfaces. Available in 10, 14, 20, or 50 mm sizes, the dollies enhance capability and resolution across different bond strengths. The testers are calibrated and certified to ± 1% accuracy with a NIST traceable load cell, and they include a Certificate of Calibration with NIST traceability.

PosiTest AT-A Key Features

Electronically controlled hydraulic pump automatically applies smooth and continuous pull-off pressure. Greatly reduces user effort and the risk of influencing the pulling process

Impact and scratch resistant color touch screen with keypad for operation with or without gloves

NEW Built-in Li-ion battery performs over 250 tests per charge.

NEW USB-C Port enables fast battery charging while simultaneously powering the instrument for uninterrupted use

Environmentally sealed enclosure—weatherproof, dustproof and shockproof—meets or exceeds IP65

Rubberized, shock absorbing grips provide a stable, skid-resistant footing

Self-aligning aluminum dolly enables accurate measurements on smooth or uneven surfaces

10, 14, 20 or 50 mm dollies maximize capability and measurement resolution across a wide range of bond strengths.

User selectable measurement units: psi (pounds per square inch), MPa (Megapascal), Nmm2 (Newtons per millimeter square) or Newton (force)

User adjustable pull rate, pull limit and hold time

Rotating display for horizontal and vertical use

Calibrated and certified to ± 1% accuracy using a NIST traceable load cell

PosiTest AT-M Key Features

Manual hydraulic pump designed to apply smooth and continuous pressure with a single stroke

NEW High-contrast, easy to read color display

Environmentally sealed enclosure—weatherproof, dustproof and shockproof—meets or exceeds IP65

Self-aligning aluminum dolly enables accurate measurements on smooth or uneven surfaces

Pull Rate Indicator to manually monitor and adjust the rate of pull
