美國Cheek-Line的TI-25M壁厚計能精確地測量壁厚，以及各種金屬，陶瓷，玻璃和硬塑料的腐蝕程度。

The TI-25M 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 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.

TI-25MX 超聲波測厚儀具有防水功能和抗沖功能，在惡劣野外環境下，也能繼續工作。
