DAKOTA NDT CMX3-DL Ultrasonic Thickness Gauge

Dakota NDT CMX2-DL & CMX3-DL Datalogging Corrosion Thickness Gauges. The Dakota NDT CMX Series corrosion thickness gauge measures coatings and material thickness simultaneously while maintaining the ability to locate pits, flaws and defects in the material. The CMX gauge offers a range of measurement modes including Pulse-Echo, Echo-Echo, Pulse-Echo Temp, Comp Mode (PETP), Coating Only Mode (CT), and Pulse-Echo Coating Mode (PECT). The gauge also allows the user to set limits for pass/fail indication on an individual reading or for each batch with audible and visual warnings. The gauge features manual or automatic gain control (AGC) with adjustable 110dB range, gate control, threshold adjustment, and differential and minimal thickness alarm modes. The CMX gauge has a choice of display modes including Readings, B-Scan, B-Scan combined with readings, and Scan bar. The CMX2-DL and CMX3-DL models also include the A-Scan display mode. The gauge’s high speed scan mode provides 250 readings per second on the CMX1 and CMX1-DL models, and 50 readings per second on the CMX2-DL and CMX3-DL models. The CMX3-DL also features A-Scan portrait and landscape views. The CMX gauge offers 64 user-defined setups, transferable to and from a PC archive. Up to 4GB of readings can be saved into the gauge memory as each measurement is taken, which can be downloaded later into an inspection application or into DakMaster software for further analysis and reporting.
