Following a 3-year development period the new ALD digital version has been completed. The performance improvements exceed expectations:

• Data are immediately converted to digital format: noise on trasmission line (ROV) is minimised
• New software version introduces the “C level”, an autocorrelation parameter which adds sensitivy to the system
• New software tools for flange inspection
• Dye detector integrated: acoustic inspection and optical inspection can now be done at once
