The Check-Line TI-25DLX 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.

Incorporates built-in datalogging for 10,000 values with 250 readings per batch, up to 40 separate batches with USB Output. Data can be transferred into any program in ".csv" format or viewed in Datacomm Software (free download)

The TI-25DLX permits the operator to select from 8 preset materials as well as program 2 custom material velocities, plus allows free adjustment of the velocity as desired and allows the end-user to calibrate to a sample of known thickness where the velocity is automatically calculated. Additionally, 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 TI-25DLX 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 calibration and other setup parameters can be locked to prevent any accidental adjustments.

The TI-25DLX 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.
