TI-25M-MMX Through Paint Ultrasonic Wall Thickness Gauge | Measuring Range in Steel
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).
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 | Simple operator controls virtually eliminate training | Special-purpose probes are offered for a variety of applications |
| Switch-selected units for inches or mm | For underwater surveying, probe cable lengths up to 50 feet are optionally | CE Certified | Includes NIST Calibration Certificate |
