TI-UMX2 Underwater Ultrasonic Thickness Gauge

Made in the USA 

Measuring Range in Steel 0.63 - 508.0 mm
0.025 - 19.99 inches

The TI-UMX2 Underwater Wall Thickness Gauge accurately measures wall thickness and the extent of corrosion of all metals at depths of up to 300 Meters (1000 feet). The TI-UMX2 also measures coating thickness.

A back-lit LCD display and illuminated housing allow divers to easily read measurements in dark water.


An over-sized control button and clever menu structure allows easy gauge setup and navigation through menus above or below water even when wearing thick gloves.

The TI-UMX-2 can store up to 5000 readings including A-Scan Waveforms and settings for each individual measurement. There are 2 file structure options; sequential with auto identifier and alpha numeric grid (row/column) format. The UMX-2 can transfer data and configuration settings to a PC using our DataComm software. (Software and transfer cable included)

Velocity Settings
The TI-UMX2 has 8 preset velocities and 1 custom velocity allowing the user to customize it for specific applications, or to tune the calibration to be optimized for a specific type of material. The list of preset velocities are as follows:

  • 1. Aluminum 2024
  • 2. Stainless Steel 302
  • 3. Steel4340
  • 4. Iron
  • 5. Cast Iron
  • 6. PVC

  • Resolution of 0.01 mm (0.001") user-selected units of inch or mm
  • Includes built-in datalogger for 5000 readings, settings and waveforms in sequential or "grid" (row/column) format
  • Automatic probe recognition and auto zero
  • Supplied with NIST-Traceable Calibration Certificate
  • Supplied with data transfer cable and data analysis software
  • Measure modes include: Pulse-Echo, Pulse-Echo w/ Coating, Echo-Echo and Triple Echo
  • CE-certified with 3-Year Warranty (90 days on probe)
  • Measures BOTH Wall and Coating Thickness
  • Both Dual Element and Single Membrane Probes are offered
  • Standard Probe supplied is 1/2"-5MHz HD-Coating, Underwater p/n T-074-2906
  • All settings for gauge and datalogging can be done via software if desired
