0.60 - 150.0 mm 

The Check-Line TI-25MX 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! It can measure thickness up to 36 inches (915 mm), depending upon the material and transducer. The TI-25MX combines the best features of the TI-25SX allowing the operator to select from 8 preset materials as well as program 2 custom material velocities. The preset materials are as follows:


  • 1. Steel 4340
  • 2. Stainless 303
  • 3. Aluminum 2024
  • 4. Cast Iron
  • 5. Plexiglass
  • 6. PVC
  • 7. Polystyrene
  • 8. Polyurethane
  • 9. Custom1
  • 10. Custom2

Additionally, the user can adjustment of the velocity as desired and calibrate to a sample of known thickness ---- the optimal acoustic velocity is automatically calculated. In special circumstances, to optimize linearity over a wide range, the user can perform a 2 point calibration to two samples of known thickness. The optimal velocity is automatically calculated to provide the highest accuracy and linearity between the low and high calibration points. The calibration and other setup parameters can be locked to prevent any accidental adjustments.

The calibration can be locked to prevent any accidental adjustments. 

The TI-25MX 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-25MX probe is waterproof and can be submerged in water. The gauge is impact-resistant and environmentally sealed (IP65) to provide trouble-free operation under the toughest field conditions.
