PosiTest^® Pull-Off Adhesion Tester

Measures adhesion of coatings to metal, masonry and other substrates - 
Revolutionary self-alignment feature brings new meaning to adhesion measurements

---

The PosiTest Adhesion Tester measures the force required to pull a specified test diameter of coating away from its substrate using hydraulic pressure. The pressure is displayed in both MPa and PSI on a precision dial indicator and can be related to the strength of adhesion to the substrate.  (click on photos for more details)

Easy-to-use Portable, hand-operated instrument can be used in any position and requires no external power source – ideal for the lab and on-site. Large, easy-to-read scale (94 mm / 3.7 in. dia.). Inexpensive, single-use dollies eliminate the need for heating, cleaning or brushing for re-use.  Each kit comes with everything needed for testing Reliable Every PosiTest Adhesion Tester pressure system is calibrated and certified to ± 1% accuracy (full scale) using NIST traceable load cell. High-quality, precision dial indicator. One year warranty. Conforms with ASTM D4541, ISO 4624 Versatile Self-aligning dolly enables measurement on smooth or uneven surfaces without adversely affecting the test results. Models available for measuring coating adhesion on any substrate.  20mm dolly ideal for metal, plastic and wood substrates, 50mm dolly ideal for masonry substrates such as concrete, etc. Custom dolly sizes available to meet specific measuring needs – contact supplier for details. Model AT-C includes unique drilling template for isolating the test area from the surrounding coating – enables testing of thick coatings. Pressure dial reads in both MPa (metric) and PSI (inch)
