ECHOMETER+

Echometer+ is our mid-level product which delivers more features and performance than the Echometer. Quick and simple to operate, it can accurately measure elongation, load, stress and strain on bolts up to 25.40 meters in length. It offers a larger digital screen than the Echometer and is easier to navigate.

Fully compatible with the Echometer including data transfer and ancillary equipment.

TRANSDUCER DATA & SELECTION
There are several things to consider when deciding which transducer to use:

  • The crystal diameter should be completely in contact with the bolt end surface.
  • The outside diameter should be clear of any obstruction.
  • The frequency should be chosen to suit the bolt length.
  • The larger the diameter the stronger the signal and therefore better results are obtained by using the largest size transducer that will fit on the bolt.
  • Boltight recommends the 3/8” diameter, 5MHz transducer as the best general purpose covering 90% or more of typical bolting applications.
