TI-CMX Ultrasonic Coating & Wall Thickness Gauge

Made in  USAWith the CHECKLINE® TI-CMX you can accurately and quickly measure both coating and wall thickness—from only one side. It is also possible to measure and eliminate the coating from the wall thickness measurement by switching the TI-CMX to the Pulse-Echo mode. This way the user can locate the finest corrosion and pitting—without removing the coating.

The TI-CMX is provided with an oversized graphic LCD which is backlit and displays fonts, graphics and display codes. It also shows all important settings like: Operating Mode, Velocity, Scan Mode, Alarms and other options. The user can set the backlight to the following settings: ON, OFF or AUTO meaning: always-on, always-off or automatically-on when measuring.

The device includes five user-selected operating modes:

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

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.

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

Coating Only: Measures coating thickness only.

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.
