Echometer & Echometer+

Boltight has been at the forefront of hydraulic bolt tensioning for over a decade. Our tensioning tools provide fast, accurate and safe solutions to tighten and loosen multiple bolts simultaneously.

Echometer & 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.
