Extensometers For Material Testing And Strain Analysis
Our extensometers are engineered for high-precision strain measurement across demanding applications:
- High Accuracy Measurement: Instruments from MTS provide reliable elongation and deformation data for tensile, compression, and fatigue testing.
- Real-World Testing Applications: Used in materials science, aerospace component validation, and automotive testing to monitor structural performance under load conditions.
- Contact And Non-Contact Options: Includes clip-on, axial, and video extensometers to suit delicate samples, high-temperature testing, and automated systems.
How to Choose the Right Extensometers
Selecting the correct extensometer requires understanding your testing requirements and sample characteristics:
- Gauge Length And Range: Choose an extensometer that matches the expected deformation range and sample dimensions.
- Contact Vs Non-Contact: Non-contact video extensometers are ideal for fragile materials or high-temperature testing environments.
- Compliance And Standards: Ensure compatibility with ASTM, ISO, or other testing standards relevant to your application.
Complete Your Materials Testing Setup
Extensometers are typically integrated into broader testing systems. Consider these complementary categories:
- Force Measuring Gauges: Essential for measuring applied load during tensile and compression testing.
- Measuring and Observing and Testing Instruments: Expand your setup with sensors and instrumentation for comprehensive data acquisition.

Frequently Asked Questions
What does an extensometer measure?
An extensometer measures strain by detecting changes in the length of a material sample during testing, providing accurate deformation data.
How does an extensometer work?
Extensometers attach to or track a sample and measure displacement as force is applied, converting this into strain values for analysis.
Can extensometers be supplied with calibration and support?
Yes, extensometers can be supplied with calibration services, installation support, and ongoing technical assistance to ensure accurate and compliant testing.
