TMI 32-25 Inclined Plane Friction Tester
Slide Angle Friction is a measurement of the angle of inclination at which one substrate affixed to a sled will begin to slide/slip against another substrate of a similar material.
TMI 68-76 Pocket Goniometer PGX+
The PocketGoniometer PGX+ is a portable, video-based instrument to determine the static contact angle at “equilibrium” or a sequence of images to measure the dynamic wetting, rate of sorption and spreading as a function of time.
