The CMX1-DL from Dakota NDT is a top-of-the-range thickness gauge for corrosion and coatings: it measures material and coating thickness simultaneously, with six measurement modes, temperature compensation and B-Scan. The CMX1 version offers the same measurement functions without the datalogger.
- Material + coating: simultaneous measurement (PECT mode)
- 6 measurement modes: P-E, PECT, PETP, E-E, E-EV, CT
- Temperature compensation: automatic (PETP)
- Pulse-Echo range: 0.63–1219 mm
- B-Scan: cross-section of the material
- 4 GB datalogger: -DL version only
- Sectors: oil and gas, energy, infrastructure, rail
The CMX1-DL non-destructively measures remaining thickness for corrosion monitoring and, at the same time, coating thickness. The dual square-wave pulser and the receiver with manual or automatic gain control (AGC) over a 110 dB range ensure reliable measurements even through paint and coatings.
Six measurement modes cover every requirement: Pulse-Echo for pitting and flaws, Pulse-Echo Coating (material + coating), automatic temperature compensation, Echo-Echo and Echo-Echo Verify (thru-paint) and Coating Only. The -DL version adds the datalogger with 4 GB of memory; the CMX version (without -DL) has no data memory.
