Ultrasound thickness surveys

We carry out ultrasound thickness measurements either as a routine part of surveying a steel or aluminium hull or as a standalone exercise.

We use a Tritex 5700 data-logging multiple-echo guage (with the same abilities as the 5600) which is excellent at reading through coatings. It even has a facility for extra thick coatings.

Here is the guage measuring a 15mm test block through six credit card type cards each 0.8mm thick and it is not on the setting for extra-thick coatings.
