The new CHECK-LINE TI-25DLXT Wall Thickness Gauge accurately measures wall thickness and the extent of corrosion of all metals, ceramics, glass and most rigid plastics from one side. When operated in E-E Mode (Thru-Paint Mode), the coating is eliminated from the reading and the gauge will display only the thickness of the metal wall.
The TI-25DLXT offers datalogging for 10,000 values with 250 readings per batch, up to 40 separate batches and USB Output. Data can be transferred into any program in CSV format or viewed in Datacomm Software (free download).
The TI-25DLXT permits the operator to select from 8 preset materials as well as program 2 custom material velocities, plus allows free adjustment of the velocityand 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-25DLXT’s 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.
The TI-25DLXT can be used with any of the following hi-damped dual-element transducers specifically designed for use with E-E Thru-Paint Mode.
T-101-2700, 3/16″ Diameter, 5.0 MHz Hi-damped transducer for thru paint measurement
T-101-3700, 3/16″ Diameter, 7.5 MHz Hi-damped transducer for thru paint measurement

T-102-3700, 1/4″ Diameter, 7.5 MHz Hi-Damped Transducer for thru paint measurement
T-104-2700, 1/2″ Diameter, 5.0 MHz Hi-Damped Transducer for thru paint measurement
T-104-9700, 1/2″ diameter, 3.5 MHz Hi-Damped transducer for thru paint measurement
