Strain Gauge Extensometers Buyer’s Guide
Strain gauge extensometers from Lloyd Instruments measure elongation and strain directly on the test sample during tensile testing, providing more accurate modulus and strain-at-break data than crosshead displacement alone. These extensometers are essential for testing to ASTM and ISO standards that require true strain measurement.

Frequently Asked Questions
Q: What does a strain gauge extensometer measure?
A: It measures the elongation or deformation of a material sample during a tensile or compression test, used to calculate strain and modulus.
Q: How is an extensometer different from a standard displacement sensor?
A: Extensometers clip or contact the sample directly to measure gauge-length change, giving more accurate strain data than crosshead displacement alone.
Q: What gauge lengths are available?
A: Gauge lengths vary by model to suit different sample sizes — check individual product specs for the exact range.
Q: Can extensometers be calibrated?
A: Yes — ICS offers A2LA-accredited calibration for extensometers as part of full material-testing-system calibration.
