TI-25M-MMX Through Paint Ultrasonic Wall Thickness Gauge

Made in the USAThe TI-25M-MMX precisely measures wall thickness of all metals, ceramics, glass and most rigid plastics and the extent of corrosion using ultrasonics. Measurements can be made from a single side!

The TI-25M-MMX has 2 measuring modes: Single Thickness Reading mode which measures the thickness on one point and the Scan mode which measures over a larger measuring area by “dragging” the probe: the minimum thickness encountered during the scan will be displayed then.

The probe of the TI-25M-MMX wall thickness gauge is waterproof and can also be submerged in water. It is ideal to use in tough field conditions because the gauge is impact-resistant and environmentally sealed..

Measuring Range:
Pulse-Echo Mode (Pit & Flaw Detection) measures from 0.63 to 152.4 millimeters. If uncoated up to 500mm with T-102-2000 probe.
Echo-Echo Mode (Through Paint & Coatings) measures from 2.54 to 25.4 millimeters (0.1 to 1 inch).

  • Resolution of 0.01 mm (0.001 inch)
  • Simple operator controls virtually eliminate training
  • Ability to measure through paint and eliminate coatings
  • Large, backlit LCD display retains last reading
  • Switch-selected units for inches or mm
  • CE Certified
  • Special-purpose probes are offered for a variety of applications
  • Includes NIST-Traceable Calibration Certificate
