Replaced by TI-25MX
Measuring Range in Steel
0.025 - 6.00 inches
0.60 - 150.0 mm
The Check-Line TI-25M 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 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.
