The Elcometer NDT CG70ABDL Corrosion Ultrasonic Thickness Gauge (part number CG70ABDL) is a handheld ultrasonic gauge for measuring remaining wall thickness on pipes, tanks and metal structures, with A-Scan and B-Scan displays for detailed interpretation. Corrosion attacks a wall from the inside where it is hidden, and a thinned section can fail under pressure. The Elcometer NDT CG70ABDL Corrosion Ultrasonic Thickness Gauge not only reports a thickness figure but shows a 2D cross sectional block view, so inspectors can locate pits and corroded areas rather than only knowing the minimum value.
The A-Scan display of the Elcometer NDT CG70ABDL Corrosion Ultrasonic Thickness Gauge lets the user view either the full waveform (RF) or a rectified waveform showing the positive or negative cycle, giving full control over how each reading is interpreted. Measurement uses Pulse-Echo (PE) and Echo-Echo (EE) ThruPaint technology, with a PE range of 0.63 to 254mm and an EE range of 1.27 to 102mm, ±0.01mm accuracy, 0.01mm resolution and a velocity calibration range of 1250 to 9,999m/s. A dual element transducer (1 to 10MHz) is driven by a square wave pulser with adjustable pulse width, and gain runs from -30dB to 70dB with automatic gain control. High speed scan mode captures 32 readings per second.
The Elcometer NDT CG70ABDL Corrosion Ultrasonic Thickness Gauge holds 6 factory and 64 user-definable setups transferable to and from a PC archive, plus basic prove-up flaw detection using single element angle beam transducers. The data logger of the Elcometer NDT CG70ABDL Corrosion Ultrasonic Thickness Gauge stores 12,000 readings with waveforms, using sequential and grid logging, alphanumeric batch identification and an OBSTRUCT marker for inaccessible locations, output over bi-directional RS232 to the Elcometer NDT data management software. Used in corrosion inspection across refineries, marine and process plant, it is supplied by BAMR, South Africa's authorised distributor.

Frequently asked questions
Can the CG70ABDL measure thickness through paint without stripping the coating?
Yes, the EE (echo-to-echo) mode is listed as ThruPaint measurement, covering 1.27 to 102mm. PE mode covers a wider range of 0.63 to 254mm for direct-contact measurement.
How does the B-Scan display help identify corrosion pits?
The B-Scan gives a 2D cross-sectional graphical view of material thickness, so pits and corroded areas show up as deviations across the scan. The combined B-Scan and digits display lets you read exact thickness alongside the cross-section.
Can I save and transfer calibration setups across gauges or work sites?
Yes. The CG70ABDL stores 6 factory setups and 64 user-definable setups, which can be transferred to and from a PC archive via the bi-directional RS232 interface.
What measurement accuracy and resolution does the CG70ABDL offer?
The gauge measures to an accuracy of plus or minus 0.01mm with a resolution of 0.01mm, across a measuring range of 0.63 to 254mm in PE mode.
How long does the battery last, and is the gauge suited to outdoor site work?
It runs on 3 x AA alkaline batteries for approximately 200 hours, with a low battery indicator and automatic battery save mode. The aluminium case has gasket sealed end caps and a waterproof membrane keypad, and operates from minus 10 to 60 degrees Celsius.
How many readings can the CG70ABDL store, and can I mark locations I could not reach?
It logs up to 12,000 readings with waveform, sequential and grid logging plus alphanumeric batch identification. An OBSTRUCT flag lets you record inaccessible locations rather than leaving a gap in the dataset.
