Air Cooled High-Temperature Extensometers

These air-cooled high-temperature extensometers are designed for measuring axial strain in high-temperature tension, compression, and through-zero fatigue testing applications up to 1200°C (2200°F).

Key Benefits

  • Includes ceramic extension rods that extend into the furnace and minimize rod creep, thermal expansion errors, and conduction losses from the specimen
  • Select from models with 100 g, 300 g, 400 g, or 780 g contact forces.
  • They exceed requirements for calibration according to ASTM E83 Class B1 and ISO 9513 Class 0.5 standards.
