CMX Thickness Gauge

A versatile ultrasonic CMX Thickness Gauge that combines the ability to measure wall thickness with or without coatings and simultaneously measure the coating itself. Time-based B-scan and large data storage capacity compliment the advanced features of this brand-new gauge.

Available in three models. Standard (CMX), with data logging (CMXDL) and with data logging, A-Scan and B-Scan display with three independent gates (CMXDL+)

Measurement Modes

  • Coating on: Pulse-Echo Coating (PECT)
  • Coating off: Pulse-Echo (P-E)
  • Temp Comp: Pulse-Echo Temperature compensated (PETP)
  • Thru-Paint: Echo-Echo (E-E)
  • Coating Only: Coating (CT)


  • Auto Probe Recognition
  • Auto Probe Zero
  • Auto Temperature Compensation
  • Adjustable Gain – (v-low, low, med, high, v-high)
  • Time based B-Scan (cross section view)
  • High Speed Scan
  • High/Low Alarm – dynamic update of both
  • Differential Mode
