Description
Reliable Pull-Off Adhesion Testing for All Surfaces
Offered through TQC Sheen, the PosiTest Pull-off Adhesion Testers are built for accurate, consistent measurement of coating adhesion on metal, wood, concrete, and similar substrates. Designed to meet multiple international standards, they are available in both manual and automatic models to suit various field and lab requirements.
Manual and Automatic Options
Both models use powerful hydraulic pumps to apply smooth, continuous pressure—either manually or via an electronically controlled system. This minimizes user influence and ensures more accurate results. The automatic model features one-button operation and adjustable pull rates for full compliance with ASTM, ISO, and other global standards.
Pumped-up Adhesion Tester Power
The PosiTest range features powerful hydraulic systems—manual or electronically controlled—delivering smooth, continuous pressure. This minimizes user effort and reduces operator variability in pull results.

Calibrated for Precision
Every unit is calibrated and certified to ±1% accuracy using NIST-traceable load cells. The self-aligning actuator and spherical dolly head ensure uniform pressure application—even on rough or uneven surfaces.
Built for Harsh Environments
With a rugged, sealed housing, the PosiTest is weatherproof, dustproof, and shockproof. It requires no external power source, making it fully portable for indoor or outdoor use.
Large Data Storage
The automatic model stores up to 100,000 pulls across 1,000 batches, while the manual model retains data for up to 200 pulls. Stored data includes pull-off pressure, pull rate, test duration, dolly size, fracture mode, and pass/fail status.
