Often times users and inspectors in the field are faced with coated
materials such as pipes and tanks. Typically inspectors will need to
remove the paint or coating prior to measuring, or allow for some fixed
amount of error introduced by the paint or coating thickness and velocity.
An A-Scan scope with a special echo -echo mode is generally used in order
to accurately perform measurements through paints and coatings.
