Measurements with THRU-COAT D7906 and D7908 Transducers

THRU-COAT is a function that measures the true metal thickness of coated or painted
parts. This function only requires a single back-wall echo and is recommended for
heavy corrosion applications where the outside of the material is coated or painted. If
needed, you can also calibrate the measurement of the coating/paint layer to precisely
measure the thickness of the coating/paint.
