Deep Coat Feature (DEEP COAT)
In Multiple Echo mode with the Deep Coat
OFF the gauge can measure through most
protective coatings up to 3 mm (0.11”)
thick, coatings like paint, anti-foul, hard
plastics and epoxy should present no
problems as long as they have not de-
laminated/de-bonded from the metal
surface.
Deep Coat On/Off Screen
In Multiple Echo mode with Deep Coat
turned ON will allow the gauge to
measure through coatings over 3 mm
(0.11”) thick up to a maximum of around
20 mm (0.78”) depending on the
properties of the coating material.
Measuring through thick coatings is
ultimately limited by how well the coating
material transmitts the ultrasound, soft
coating like rubber or bitumen don’t
transmit ultrasound very well.
If you need to measure through a coating
over 3 mm thick then you will have to
turn Deep Coat ON. Using Deep Coat will
not affect the calibration.
Note. Deep Coat is only available in
Multiple Echo mode.
To turn Deep Coat on or off select DEEP
COAT from the Main Menu.
A warning message is
flashed at the top of the
measurement screen
when Deep Coat is turned
on.
