Elcometer 508 Push Off Adhesion Tester

The Elcometer 508 Push Off Adhesion Tester is an extremely versatile Type III* adhesion gauge which can be used to test adhesion strength of coatings.

Tests can be made on flat or curved (concave and convex) surfaces.


  • Hand-held, ergonomic and fully portable - ideal for on-site adhesion testing
  • Quick connect coupling for easy connection to the dolly
  • Measurement range up to 25MPa (3630psi) with a full scale accuracy of  ±1.5%
  • Rotating crank handle applies smooth loading from 0 up to 25MPa (3630psi)

Standard, convex and concave dollies can be used with the Elcometer 508 adhesion gauge, ideal for testing the adhesion of coatings on flat or curved surfaces such as pipelines and tanks.


  • Suitable for use on flat, concave & convex surfaces
  • Rugged & lightweight
  • Smooth load application up to 25MPa (3630psi)


  • Easy to use hand-held design
  • Ideal for field use on tanks & pipelines
  • Reusable stainless steel dollies
  • MPa / psi switchable


  • Sealed, heavy duty & impact resistant
  • Dust & waterproof equivalent to IP65
  • Suitable for use in harsh environments


  • Measurement range up to 25MPa (3630psi)
  • Full scale accuracy of ±1.5%
  • Maximum hold - displays the highest value reached


Adhesion Tester Adhesion Testing Adhesion Test Kit
The rubber protected backlit digital LCD displays the reading in MPa or psi. Maximum hold feature displays the highest value reached.  Flexible cable design allows the coupling to be positioned easily over the dolly. The pin is pushed through the centre against the substrate providing accurate repeatable results. Supplied in a robust plastic carry case, the kit includes the Elcometer 508 and five dollies which can be cleaned with the heated tongs.


* Type III in accordance with ASTM D 4541
