The long travel extensometer is designed for testing ductile materials such as elastomers, flexible plastics, foils, textiles and leather. Even with whiplash-prone specimens, the solid mechanical construction of the guide elements ensures safe and reliable operation.

This extensometer is used for direct strain measurement in tensile and hysteresis tests on specimens with medium or high extension and is also suitable for testing in temperature chambers, using extended sensor arms.

• High resolution over the entire measurement range.
• Accommodates large measuring range, up to 1000 mm.
• Very low drag forces.
• Robust construction and non-impact-sensitive measuring system.
• Minimal transmission errors due to low-friction mounting of the measuring slide carriage.
• Can be combined with any analog or digital clip-on extensometer or with a manual transverse strain extensometer.
• Fulfils the requirements of EN ISO 9513 Accuracy Class 2 and Class 1 from  1 mm.
