PosiTest®
AT Digital
Coating
Pull-Off
Adhesion Tester
By DeFelsko
Measures adhesion of
coatings to metal, wood, concrete, other substrates.
With revolutionary self-alignment feature and pull rate indicator.
|
Now Digital... PosiTest
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 Mpsi and MPa on a precision digital indicator. |
| Simple |
- Portable, hand-operated instrument
requires no external power source - ideal for lab and field use.
- NEW... Large, easy-to-read LCD.
- NEW... Pull Rate Indicator - allows
operator to easily monitor and adjust the rate of pull in accordance
with international test methods.
- NEW... Easily select dolly sizes,
change measurement units or store readings, with the touch of a
button.
- NEW... Conversion charts not
required - tester automatically calculates pressure based on dolly
size.
- Inexpensive, single-use dollies
eliminate cleaning for 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, ISO 4624
and others.
|
| Versatile |
- NEW... Internal Memory stores
maximum pull-off pressure, rate of pull, test duration and dolly
size for up to 200 pulls.
- NEW... Optional PosiSoft® software
available for downloading to a computer.
- 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 be
uniformly distributed over the surface being tested.
The Self-Aligning Dolly enable
uniform distribution of the pulling force over the surface being
tested, preventing a one-sided pull-off. |

 |
| Test Dollies: The
PosiTest Adhesion Tester uses inexpensive single-use aluminum
dollies designed according to internationally accepted standards and
practices. Available with full 10, 14, 20 or 50 mm surface diameters
for different shapes and bond strengths. |
