The Defelsko PosiTest AT-M 20mm Pull-Off Adhesion Tester is a portable adhesion Tester that uses the hydraulic pulling force of the adhesIon Meter to peel the coating per unit area from the coating substrate, suitable for use in laboratories and workshops and other occasions, and displays readings in Psi and MPa units through the LCD screen, with a measurement range of 0~3000 psi adhesion strength, water and dust resistance, and a good hose with 1.5 m long can be used to measure narrow areas.


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. Simple operation
●Portable hand-held pull-off adhesIon Meter, no external power supply, 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.
3. Accurate
●The pressure system of the PosiTest AT-M 20mm pull-off adhesion Tester is calibrated by the NIST load cell with a measurement accuracy of ±1%.
●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.
