The CHECK-LINE TI-UMX2 Underwater Wall Thickness Gauge accurately measures the wall thickness of all metals, extent of corrosion and the thickness of coatings on them -- at depths of up to 1000 feet (300 Meters). 

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
  7. Polystyrene
  8. Polyurethane
  9. Custom 1
