Digital pull-off adhesion tester - SADPO500


Digital pull off adhesion tester is an easy to operate, fully portable tool for coatings adhesion measurement. The operation principle is based on tensile dollies that are glued to the coating; once the adhesive has cured the force required to pull the dolly off the surface is measured. The force applied perpendicularly to the surface is gradually increased and monitored until the coating breaks down, or until a predetermined value is reached. Pull off tester employs hydraulic pressure in order to assess the force needed to detach the dolly from the coating surface. The test determines either the greatest perpendicular force (in tension) that a surface area can bear before a plug of material is detached, or whether the surface remains intact at a prescribed force (pass/fail). Failure will occur along the weakest plane within the system comprised of the test fixture, adhesive, coating system, and substrate, and will be exposed by the fracture surface. This test method maximizes tensile stress as compared to stress applied by other methods, such as scratch or knife adhesion, and results may not be comparable.



Portable design, built-in rechargeable lithium battery, no need external power supply, can be used in any position; 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 for re-use and can be kept as a permanent record; each kit comes with everything needed for testing.



Every adhesion tester pressure system is calibrated and certified to ± 1% accuracy using NIST traceable load cell; self-aligning aluminum dolly enables accurate measurements on smooth or uneven surfaces; hi-grade (industrial pressure sensor) ensures continued accuracy; built in real-time clock, all reserved data has its own data and time, is convenient for operator to manage test data - the operator can manage better the recorded data.



Environmentally sealed enclosure weatherproof, dustproof and shockproof - meets or exceedes IP65; rugged carrying case.



Internal memory (200 pulls) stores maximum pull-off pressure, rate of pull, test duration and dolly size; no need any software, when connecting the PC operator can read directly all data recordered during testing; LCD displays pressure value in psi or mpa; 10, 14, 20 or 50 mm dollies maximize capability and measurement resolution across a wide range of bond strengths.
