A friction tester, also called a coefficient-of-friction (COF) tester, makes a measurement of a sheet-like substrate such as paper, corrugated, plastic film or paperboard which determines the angle of inclination at which one substrate affixed to a sled will begin to slide/slip against the surface of another substrate of a similar material.

Specifications:

• 0 to 80º angle
• Conforms to TAPPI T-815 and ASTM D202 with optional sliding blocks
• Motor-driven elevation
• Simple, low-cost measurement of static COF
• Photo sensor automatically stops the test after initial sled movement
• Measures only Slide Angle or Coefficient of Static Friction
