The Elcometer NDT CG100BDL Corrosion Ultrasonic Thickness Gauge (part number CG100BDL) is a handheld ultrasonic gauge that measures material thickness, detects corrosion and logs readings across a full range of measurement modes, including B-Scan cross-sectional imaging. The Elcometer NDT CG100BDL Corrosion Ultrasonic Thickness Gauge suits inspectors who need both flexible measurement methods and a stored record of their results.
Internal corrosion thins the walls of pipes, tanks and structural steel where the eye cannot reach, so confirming remaining wall thickness is what keeps assets safely in service. The Elcometer NDT CG100BDL Corrosion Ultrasonic Thickness Gauge reads thickness using Pulse-Echo (PE), Temperature Compensation (PETP), Echo-Echo ThruPaint (EE), EEV, Coating Only (CT) and Pulse-Echo Coating (PECT) modes, measuring true metal thickness through paint or coating and substrate together. Time corrected gain compensates for sound attenuation, automatic gain control eases set-up, and threshold adjustment raises sensitivity to lower-amplitude signals so corroded back walls are still detected.
The PE measuring range of the Elcometer NDT CG100BDL Corrosion Ultrasonic Thickness Gauge 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 CG100BDL Corrosion Ultrasonic Thickness Gauge stores up to 16,000 readings with individual waveforms in alpha-numeric batches, with full data logging through bi-directional RS232 output to Elcometer NDT data management software. The Elcometer NDT CG100BDL Corrosion Ultrasonic Thickness Gauge carries 6 factory and 64 user-definable setups, a dual element transducer at 1 to 10MHz and a quarter-VGA grayscale display, with around 150 hours of battery life. The CG100BDL is supplied by BAMR, South Africa's authorised Elcometer distributor.

Frequently asked questions
When should I use Pulse-Echo Temperature Compensation (PETP) instead of standard Pulse-Echo?
Use PETP when temperature variations affect your measurement area, as it compensates for changes in material velocity. Both modes measure from 0.63 to 508 mm with ±0.01 mm accuracy.
Can I measure coating thickness independently from the substrate material?
Yes. Coating Only (CT) mode measures coatings from 12.7 to 254 micrometres independently. Pulse-Echo Coating (PECT) mode simultaneously captures both coating and substrate thickness on a single measurement.
What measurement accuracy does the CG100BDL deliver?
The gauge delivers ±0.01 mm accuracy with 0.01 mm resolution across all thickness modes. This precision meets QC requirements for both coating and substrate inspection.
Will the CG100BDL work reliably in cold or hot field conditions?
The gauge operates from -10 to 60 °C and runs approximately 150 hours on three AA batteries. Its sealed design with waterproof keypad and gasket-sealed end caps protects against moisture and rough handling.
How do I manage and export measurement records for audit trails?
The CG100BDL logs 16,000 readings with B-scan images or 210,000 thickness records in sequential, grid, or batch formats. Data exports via RS232 interface and the OBSTRUCT feature marks inaccessible measurement locations.
