General Description:

Now Digital...Measures adhesion of coatings to metal, wood, concrete and other substrates - Revolutionary self-alignment feature and pull rate indicator 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 on a precision digital indicator and can be related to the strength of adhesion to the substrate.
Simple
•    Portable, hand-operated instrument requires no external power source – ideal for lab and field use.
•    Large, easy-to-read LCD
•    Pull Rate Indicator – allows operator to easily monitor and adjust the rate of pull in accordance with international test methods.
•    Easily select dolly sizes, change measurement units or store readings, with the touch of a button
•    Conversion charts not required – tester automatically calculates pressure based on dolly size
•    Inexpensive, single-use dollies eliminate cleaning re-use and can be kept as a permanent record
•    Each kit comes with everything needed for testing
Self-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. Self-Aligning Dolly enables uniform distribution of the pulling force over the surface being tested, preventing a one-sided pull-off.

•    PosiSoft 3.0 - desktop software for downloading, viewing, printing and storing measurement data.
•    10, 14, 20 or 50 mm dollies maximize capability and accuracy across a wide range of bond strengths
•    LCD displays pressure value in psi or MPa
Self-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.
The PosiTest Adhesion Tester compensates for misalignment. 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.
Test Dollies: The PosiTest Adhesion Tester uses inexpensive single-use aluminum dollies designed according to internationally accepted standards and practices. They have a full 20 or 50 mm surface diameter with no holes to clean or keep from filling with adhesive
