Defelsko PosiTest AT-M 50mmThe pull-off adhesion Tester is a manual pull-off adhesion Tester that uses a 50mm size jack and is suitable for measuring adhesion coatings with lower adhesion such as wood paints, concrete coatings, and plastic paints.The PosiTest AT-M 50mm Pull-Off Adhesion Meter has a measurable range of 50~500psi, which is narrower than the measurement range of the 20mm top model, and is a digital display test result with a display resolution of 0.01MPa. The adhesIon Meter is equipped with a good hose for measuring difficult areas and has a USB interface for connecting to a PC.
The structural components of the Defelsko PosiTest AT-M 50mm pull-off adhesion Tester are: 1.5 m good hose, USB port, pull-out head, manual hydraulic pump, quick sleeve, LCD display.
Among them, the role of the quick sleeve is:The PosiTest A Adhesion Tester uses the bearing balls inside the sleeve to quickly lock the tip of the spindle to ensure accurate positioning, resulting in a balanced pull-out force.

The PosiTest AT-M 50mm Pull-Off Adhesion Meter complies with ATSM D4541 and ISO 4642 standards.
The PosiTest AT-M 50mm Pull-Off Adhesion Meter is the amount of tension required to separate a coating per unit area from a collective, expressed in MPa or Psi.

1. Durable
●It has the advantages of waterproof, dustproof and impact-proof.
●Good hydraulic pump is not afraid of any Operating Environment.
● With a sturdy carrying case.
2. Accurate
●The pressure system of the PosiTest AT-M 20mm Pull-Off Adhesion Meter is calibrated with a ±1% accuracy by a force cell from the Velocity NIST.
●High-grade industrial pressure sensors ensure continuous high accuracy.
● Self-aligning positioning jacks for equally accurate measurements on smooth or rough surfaces.
●Pull-off adhesion Tester complies with ASTM D4541, ISO 4624 and other test standards.
3. Simple operation
● Portable handheldPull-off adhesion Tester does not require external power supply, and is suitable for use in various occasions such as laboratories and workshops.
● Large LCD display, easy to read.
●Standard configuration can meet general testing needs.
●The top sub-model can be selected by pressing a button, changing the unit of measurement or storing the reading.
● There is no need to change the table, the pull-off adhesIon Meter will automatically calculate the pressure value according to the size of the jack.
●The top is of low value and can be stored for a long time as an archive, eliminating the trouble of cleaning caused by repeated use.
4. Diverse functions
● The built-in memory can store up to 200 data, including tensile value, pressurization rate, test time, and top size.
● PosiSoft software is optional.
● LCD LCD display, Psi or MPa units can be selected.
●Available in 10, 14, 20 and 50 mm jacks to meet the testing needs of different adhesion ranges.
