Pulse-Echo Mode (Pit & Flaw Detection) measures from 0.025 to 19.999 inches (0.63 to 500 millimeters)
Echo-Echo Mode (Through Paint & Coatings) measures from 0.1 to 1 inch (2.54 to 25.4 millimeters)
(range depends upon probe selected)
The new CHECK-LINE TI-25M-MMX Wall Thickness Gauge accurately measures wall thickness and the extent of corrosion of all metals, ceramics, glass and most rigid plastics - from only one side!
The TI-25M-MMX can be used in a Single Thickness Reading mode or in a Scan mode , where the probe is dragged over a large measuring area. The minimum thickness reading recorded during the "scan" will be displayed.
The TI-25M-MMX probe is waterproof and can be submerged in water. The gauge is impact-resistant and environmentally sealed to provide trouble-free operation under the toughest field conditions.
- Ability to measure through paint and eliminate coatings
 - Resolution of 0.001 inch (0.01 mm)
 - Large, backlit LCD display retains last reading
 - CE-Certified

 - Switch-selected units for inches or mm
 - For underwater surveying, probe cable lengths up to 50 feet are optionally
 - RS-232 output to transfer individual data values
 - Includes NIST-Traceable Calibration Certificate
 - IP 65 Rated
