TI-CMXDL Data-Logging Ultrasonic Coating & Wall Thickness Gauge

Made in USA
TI-CMXDL Through Paint Ultrasonic Thickness Gauge with Data Logging
Click images to enlarge.
The Check-Line TI-CMXDL accurately measures coating and wall thickness on a wide range of materials. Five selectable measuring modes enable the operator to precisely measure wall thickness, coating thickness and locate corrosion and pitting—without removing the coating.

Oversized graphic LCD is backlit and features an easy to navigate menu allowing quick access to gauge settings and options.

Five user-selected operating modes are included:

Coating On: Measures wall thickness using Pulse-Echo. It separately displays wall & coating thickness.

Coating Off: Measures wall thickness using Pulse-Echo. It displays wall thickness only.

Temperature Compensated: Measures wall thickness using Pulse-Echo and automatically adjusts calibration to compensate for changes in material temperature.

Thru-Coat: Measures wall thickness only using Echo-Echo. (coating is NOT included)

Coating Only Mode (CT): (Coating Thickness) Measures from 0.0005 to 0.100 inches (0.013 to 2.540 mm). Range will vary slightly depending on the coating.

Special Features of TI-CMXDL Data-Logger

  • Built-in memory with RS-232 output for transferring data to a Printer or PC

  • Includes Datacomm Data Transfer & Analysis Software and RS-232 Cable, FREE

  • Data Files can be user-set for a "grid type" structure where data is formatted in Rows & Columns or a "sequential" file where all data appears in a single column

  • Each "grid type" File can be set for up to 999 rows by 52 columns

  • Each "sequential" File can be set for up to 512 rows by 1 column

  • Each File can be set for "data only" or as "data plus B-scan Graphic". Memory Capacity is over 225,000 data values or over 16,000 data values with B-scan


  • Includes NIST-Traceable Calibration.
  • Auto probe recognition with Auto Zero or Manual Zero.
  • Wide variety of dual-element probes can be used for nearly any application.
  • Bar graph with user-set start end values providing highest resolution around the target thickness value.
  • Differential Mode allows user to set a "target thickness value" and display will show the DIFFERENCE between actual and target thickness as a plus or minus value.
  • TI-CMX-H for surface temps up to 300°F/150°C. Optional hi-temp probes for higher surface temperatures offered
  • Adjustable Gain in 5 steps (VLow, Low, Med, Hi & VHi) in 2db increments providing a 8 db gain adjust range (42–50 db).
  • 64 custom setups can be stored and retrieved for convenient use and labeled for easy identification
  • Display Hi/Lo Alarm Limits with audible and visual indicators.
  • Metal housing provides strong protection against harsh environments.
  • Measures Coatings up to 0.100"
  • IP 65 Rated
  • CE Certified
  • Warranty: Gauge: 2 Years Probes: 90 Days
  • Made in USA

High Speed Scan Mode & B-Scan Mode

Hi-Speed Scan Mode B-Scan Mode
High Speed Scan Mode B-Scan Mode
Scan Mode measures 64 times per second, displaying the max and min reading measured during the scan interval. Sample rate is 200/sec when coating measurement is off. The B-Scan displays a time based cross section view of test material of the contour of the blind, or underside of a pipe or tank application. the B-Scan view draws at a rate of seven seconds per screen from right to left.
