POSITEST-ADHESION-TESTER PosiTest Pull-Off Coating Adhesion Tester
The PosiTest adhesion tester determines the adhesion of a coating or paint layer to its substrate. This destructive adhesion test method works as follows; a metal dolly is glued to the coating or paint layer and is pulled from the substrate vertically with help of the hydraulic adhesion tester.
The pulling mechanism of the PosiTest adhesion tester is self-aligning to make sure the dolly is pulled perfectly vertical under every circumstance, producing reliable, repeatable measurements. Peeling of the dolly producing incorrect results is prevented with this mechanism.
The norm for adhesion testing prescribes the maximum pull rate, pulling too fast results in incorrect measurements. The adhesion tester is equipped with a pull rate indicator preventing the user from pulling the coating from the material too fast.
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
Durable
- Weatherproof, dustproof and shockproof
- Quality hydraulic pump can be used in any position
- Rugged carrying case
- One year warranty
Accurate
- Every PosiTest adhesion tester pressure system is calibrated and certified to ± 1% accuracy using an NIST traceable load cell
- Self-aligning dolly enables accurate measurements on smooth or uneven surfaces
- Hi-grade, industrial pressure sensor ensures continued accuracy
- Conforms with ASTM D4541/D7234, ISO 4624, SSPC-CS 23.00/AWS C2.23/NACE No. 12, and others
Versatile
- Internal Memory stores maximum pull-off pressure, rate of pull, test duration and dolly size for up to 200 pulls
- Optional software available for downloading to a computer
- LCD displays pressure value in psi or MPa
- 10, 14, 20 or 50 mm dollies maximize capability and accuracy across a wide range of bond strengths
