The CMX2-DL from Dakota NDT is a two-channel thickness gauge for corrosion and coatings with A-Scan and B-Scan display: 100 MHz DSP platform, 110 dB of gain and six measurement modes. The CMX2 version offers the same functions without the datalogger.
- Two channels: dual pulsers and receivers
- A-Scan and B-Scan: waveform and cross-section
- Material + coating: simultaneous measurement (PECT)
- 6 measurement modes: P-E, PECT, PETP, E-E, E-EV, CT
- 110 dB gain: manual and automatic (AGC), TDG
- Transducers 1–20 MHz: single, dual, delay line, pencil
- 4 GB datalogger: internal memory, screen capture
The CMX2-DL is a two-channel thickness gauge (dual pulsers and receivers) built on a 100 MHz DSP platform with FPGA technology. The A-Scan display shows the ultrasonic waveform and the B-Scan a cross-section, for accurate assessment of remaining thickness and of coatings.
It offers six measurement modes (P-E, PECT, PETP, E-E, E-EV, CT), gain adjustable over 110 dB with AGC and linear TDG, and 4 GB of internal memory. The CMX2 version (without -DL) has no datalogger.
