Claw Transducers

The extendible small diameter transducer or “Claw” is able to fit between closely spaced tubes where conventional rings cannot fit.

There is also a remote access option where the tool head is attached to a 2-metre-long extension arm that allows inspection of difficult to access tubes or pipes.

Different transducer spacing options are available.
