Description
The TA3542 Extensometer is designed for use with a variety of materials including materials, including metals, plastics, and composites. This is a general use strain gauge extensometer for axial tensile and compression. Featuring a gauge length from 10 to 80 mm and full-scale measuring ranges from 5% to 100% strain.
Common Industry Standards:
- ISO 6892-1, 527-2, 527-4, 527-5, 10113
- ASTM E8, E9, D3039, D638, A370, D3552, E517, E646
Features:Â Â
- May be left on through specimen failure.
- Full bridge, 350 ohm strain gaged design for compatibility with nearly any test system.
- All models can measure both tension and compression.
- Standard quick attach kit allows one-hand mounting to samples.
- All models have mechanical overtravel stops in both directions.Â
- Replaceable hardened tool steel knife edges – includes one spare set. Â
- Gauge length adapter kits are available to work with multiple gauge lengths with one extensometer.
- Replaceable arms and spacers for easy repair.
