Compact and portable, this ultrasonic tool quickly and accurately measures bolt elongation.

Echometer and Echometer +

Echometer and Echometer+ use ultrasonics to measure the elongation, stress and load in fasteners. They offer quick and accurate measurements with readings displayed on an easy to read screen. The units work with all bolt tightening systems and are used to monitor the fastener during the tightening process to ensure accurate initial loading. The retained load in the fastener can then be monitored at any time.


  • Echometer+ delivers more features and performance than the original handheld Echometer.
  • The device can accurately measure elongation, load, stress and strain on bolts of up to 25.40m.
  • The device has nine different pulse width options to select from and a new automatic correlation feature.


  • Simple to operate
  • Compact and durable for proven reliability
  • Minimal operator training required
  • Provides elongation, load, stress and strain measurements
  • Accurate and reliable
  • Designed to complement Boltight bolt tensioning
  • Easy measure during tightening and monitoring during plant operation
  • Cost effective
  • Simple data recording and reporting
