Wet Abrader / Wet Wear Tester

Built on a combination of the RCA Abrader design, and the Finger Pressing design of the Pneumatic Finger Tester, this Wet Abrader adds the ability to apply a liquid to a special NTI Abrasive Media. This abrasive media is then pressed and rubbed against the specimen using a silicone finger probe. The test probe conforms to ASTM 1578 and ASTM 1597 Fig. 1.

This abrader can test the abrasion resistance of inks and coatings on a variety of items including membrane switches, silicone keypads, computer keys, buttons, or any item that is repeatedly pressed or in contact with the human finger in a wet or dry state. This abrasion wear tester can also help support the test standard ASTM 1597 “Determining the Actuation Force and Contact Force of a Membrane Switch”.


  • Easy set-up and operation
  • Automatic shut-off
  • Adjustable pressure loads and length motion
  • Abrasion Debris does not affect test
  • Continuously uses inexpensive unused abrasive media
  • Can be run wet or dry
