and machinery and for persons who might use these in design and technology facilities in all types of educational establishments

It’s particularly useful for detecting discontinuities – such as pores and other defects – in certain metallic

It's used for the most critical applications and advanced analytical procedures

A work station is occupied by an operator and may be located in open space, in the room where the source under test operates, in a cab fixed to the source under test, or in an enclosure remote
