Axial Extensometers

General purpose extensometers for axial tensile, compression, and cyclic testing. Gauge lengths from 10 to 80 mm (and 0.5 to 2 inches) and full scale measuring ranges from 5% to 100% strain.

Gauge Lengths: 10 – 80 mm
Measuring Ranges: 5% – 100%
Temperature Range: -270 °C to 200 °C with LHT option
Key Features: Durability, quick attach

Small profile and ultra-light weight, these units are appropriate for testing small and delicate samples yet rugged enough for daily use on standard specimens. Ideal for wire specimens, sheet materials, and standard ASTM or ISO specimen geometries, and excellent for low and high cycle fatigue testing.

Gauge Lengths: 3 – 50 mm
Measuring Ranges: 5% – 100%
Temperature Range: -270 °C to 200 °C with -LHT option
Key Features: Low profile, durability, light weight

Long gauge length extensometers with gauge lengths 100 mm (4 inches) orgreater for tensile and compression testing. These units are for long gage length applications where low level strain measurements such as offset yield are required.

Gauge Lengths: 100 – 600 mm
Measuring Ranges: ±2.5 mm up to +25.0 mm/-6.0 mm
Temperature Range: -270 °C to 200 °C with -LHT option
Key Features: Extra-long gauge length

Measures average axial strain. Features self-setting gauge length.

Gauge Lengths: 10 – 50 mm
Measuring Ranges: ±0.5 mm, ±1 mm, +2.5 mm
Temperature Range: -270 °C to 200 °C with -LHT option
Key Features: Self-setting gauge length, compact

Designed for plastics, rubber and elastomer testing, these extensometers have very long measuring ranges. Their unique design allows testing to failure and minimizes interaction with the sample.

Gauge Lengths: 20 – 50 mm
Measuring Ranges: +250 mm and +500 mm
Temperature Range: -40 °C to 100 °C
Key Features: High elongation extensometer
