TI-25M-UWM Underwater Ultrasonic Thickness Gauge

The TI-25M-UWM Underwater Ultrasonic Thickness Gauge is no longer available and has been replaced by TI-UMX2.
Click here to see the TI-UMX2.

Made in the USAMeasuring Range
0.60 - 150.0 mm
0.025-6.00 inches

The CHECKLINE TI-25M-UWM Underwater Wall Thickness Gauge accurately measures wall thickness and the extent of corrosion of all metals at depths of up to 91.44 M (300 feet).

The TI-25M-UWM 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.

  • Resolution of 0.01 mm (0.001 inch)
  • Large, backlit LCD display retains last reading
  • Simple operator controls virtually eliminate training
  • Special-purpose probes are offered for a variety of applications
  • 91 M (300 feet) depth rating
  • Clear plexiglass construction, Stainless steel connectors, latches, and control bar
  • Switch-selected units for inches or mm
  • CE Certified
  • NEW Elastic wrist strap secures the gauge during dives

Complete Kit
The TI-25M-UWM is supplied as a complete kit including:
- gauge, underwater enclosure, underwater transducer, coupling fluid, instruction manual and calibration certificate in a foam lined hard plastic carrying case.
