E-EAGCB-ScanA-ScanThe CG70 range of corrosion thickness gauges withits large, easy to read display, provides users with
A and B-Scan options for accurate interpretation ofmeasurements.
The Elcometer CG70 corrosion thickness gauge isavailable in two models: CG70BDL and CG70ABDL.
Both models offer 2D cross sectional block view, providing
a graphical representation of a material’s thickness, ideal
for accurate analysis and identification of pits and corroded
areas.

The gain control function in Echo-Echo mode automaticallyadjusts the amplitude of the received echo, but it can beoverridden using the selectable low, medium and highgain options to suit the properties of the material being
measured, ideal for difficult applications.
As well as all the features of the CG70BDL, the CG70ABDL
also features an A-Scan display, allowing users to fullyinterpret and control measurement readings. The user
can select to view either the full waveform (RF) or therectified waveform (RECT) showing either the positive or
the negative cycle of the full waveform.

The CG70 gauges take 32 readings per second in scanmode. The internal data logger stores up to 12,000
readings together with their waveforms. RS232 output toElcoMaster® data management software allows ease ofanalysis and professional reporting.
The CG70 range has 64 user definable setups and works
with a wide range of transducers which can be selected fromthe gauges internal menu. For a full range of transducers,
please refer to the Dual Element Transducers data sheet.
