The Elcometer NDT CG100ABDL Corrosion Ultrasonic Thickness Gauge (part number CG100ABDL) is a handheld ultrasonic gauge that measures material thickness and detects metal loss using a full range of measurement modes, including A-Scan and B-Scan imaging. It is used by inspectors who need to choose the right measurement method for the material and condition in front of them.
Corrosion thins the walls of pipes, tanks and structural steel from the inside, and missing that loss can lead to leaks or structural failure. The CG100ABDL provides Pulse-Echo (PE), Temperature Compensation (PETP), Echo-Echo ThruPaint (EE), EEV, Coating Only (CT) and Pulse-Echo Coating (PECT) modes, so the inspector can read true metal thickness through paint, or measure coating and substrate together. Automatic gain control simplifies set-up, while manual gain adjustment from minus 30dB to 70dB and time corrected gain compensate for sound attenuation in difficult materials. Three fully adjustable gates and threshold adjustment let users ignore surface echoes and noise.
The PE measuring range is 0.63 to 508mm, with accuracy of plus or minus 0.01mm, 0.01mm resolution and a velocity calibration range of 1250 to 13,995m/s. Scan mode runs at 50 readings per second. The Elcometer NDT CG100ABDL Corrosion Ultrasonic Thickness Gauge stores up to 16,000 readings with waveforms and B-Scans across 6 factory and 64 user-definable setups, with bi-directional RS232 output to Elcometer NDT data management software. It uses a dual element transducer at 1 to 10MHz and a quarter-VGA grayscale display. The CG100ABDL is supplied by BAMR, South Africa's authorised Elcometer distributor.

Frequently asked questions
When should I use Coating Only mode rather than Pulse-Echo Coating mode?
Coating Only (CT) measures coatings alone from 12.7 to 254 micrometres. Pulse-Echo Coating (PECT) measures both coating thickness (0.01 to 2.54mm) and substrate material (0.63 to 508mm) in one reading. Use CT for coating-only verification; use PECT when you need both measurements in a single setup.
Can I measure material thickness without removing protective coatings?
Yes, use Through-Paint (EE) mode to measure material thickness through coatings up to 102mm range. For substrate plus thin coating in one reading, PECT mode covers substrate 0.63 to 508mm and coating 0.01 to 2.54mm.
What measurement accuracy should I expect from the CG100ABDL?
Measurement accuracy is ±0.01mm with 0.01mm resolution. The gauge includes a repeatability/stability indicator to confirm readings are consistent, which matters for QC documentation and traceability.
Can I transfer calibration setups between instruments or save them to a PC?
Yes. The gauge stores 6 factory calibrations plus 64 user-defined setups transferable to and from PC archive software. This simplifies maintaining consistent calibration across multiple sites or customer deployments.
Does the CG100ABDL log inspection data for compliance records?
The gauge logs up to 16,000 readings with A/B-scan images included. Sequential or grid logging modes with batch identification and OBSTRUCT markers for inaccessible areas support your traceability requirements.
