DM4 and DM4 DL D-Meter Thickness Gauges...

thickness testing, even through coated materials!

Now, the DM4 and DM4 DL are capable of

measuring through coatings (paint) without

the coating layer being included in the digital

thickness reading. Simply press the DUAL

MULTI key and read the remaining metal

thickness without the time and expense of

removing protective coatings and reapplying.

The DUAL MULTI, dual-element/multiple echo

measurement mode is “unique” to the DM4

and DM4 DL handheld digital thickness

gauges. The same dual-element probes

that provide best results on internally

corroded/eroded structures and general

thickness applications in the standard

thickness mode are used. No special

probes, switching of probes, or compli-

cated operation or interpretation is

necessar y.

If multiple backwall echoes are not possible on

your application, the coupling indicator will not

illuminate, the display will blank, and the red LED

will flash. Then, a simple press of the DUAL MULTI

key will return the instrument to the standard

thickness mode. Whether or not to remove paint is

then a decision that will need to be made.

Measure on rough and corroded surfaces

The DUAL MULTI mode is also a good method to

use to overcome coupling problems and errors

encountered when measuring on rough and

corroded sur faces. The heavier couplant layer

that is typically required to obtain measurements

on rough sur faces is not included in the digital

thickness reading. Sur face preparation is elimi-

nated or minimized.

Dual Multi measurement is made between backwall echoes from the

metal, and the echoes from the coating (paint) layer are ignored.
