This unique digital clip-on extensometer is suitable for precise modulus and yield point determination to ISO 527-1 for rigid and semi-rigid plastics and for determining strain at maximum stress plus strain at break on rigid plastics with low extension. It can additionally be used to determine the compressive strength of plastics or the compression E-modulus on metals.

• Adjustable initial gage lengths.
• Initial gage length is automatically locked at clip-on and unlocked at release.
• Provides high-resolution E-modulus determination to ISO 527-1.
